IntroductionThis Product Catalogue provides comprehensive information about Series AM

Comfort fan convector heaters and guidance on selection, application, use andsupply.

Each heater consists of a casing, motor/fan platform, air filter and heating

coil. Depending upon the model, grilles are either fitted to the casing or can be

supplied loose for fitting by others.

Heaters provide warm air heating, when connected to a low or medium

temperature hot water system and a single phase electrical supply. A simple

product description code is used to identify heaters and accessories. Each heater

has a unique serial number.

For low grade heating mediums and low surface temperature options refer to the

Avant-Garde & LST fan convector brochures.

AuthorityDunham-Bush operates a quality control system and is a registered firm of

assessed capability BS EN ISO 900 : 000.

Each Series AM Comfort fan convector comprises a sheet metal casing with

lockable access panel, motor/fan platform, auto transformer, air filter and hot

water heating coil. A single phase electric heater coil can be supplied instead of

the hot water coil on heaters with an output up to 6kW. Depending upon the

model selected, grilles are either fitted to the casing or can be supplied loose as anaccessory, for internal use.

Heaters are supplied for single or dual fan speed operation. Single speed heaters

are set to low, medium or high speed. Dual speed heaters are set to low/medium,

low/high or medium/high speeds. Fan/heat control is by means of switches and/or

thermostats, listed in the Accessories section of this Product Catalogue.

RangeThe range consists of standard models, arranged in 4 groups floor, wall,

Air thermostatsAir thermostats can be provided to automatically switch the heater on/off and/or

to change the fan speed/heat output, in response to a fall or rise in ambient airtemperature.

Fitted air thermostats, Models 3, 5, 7, 0, , 3 and 5 only.Capillary thermostats or room thermostats with accelerator heater, can be fitted for

on/off and speed change control.

Remote thermostatsStandard or tamper resistant room thermostats with accelerator heater, can be

provided for on/off and speed change control.

Low temperature cut-out thermostat (LTC)A low temperature cut-out thermostat can be provided to prevent the heateroperating until the heating water temperature is hot enough for it to work

efficiently. This thermostat will automatically stop the heater at the end of the

normal operating period, when the boiler plant closes down.

Type 1, fixed setting LTC, break circuit 38C3K, make circuit 50C3KIf fitted, type is wired into the control circuit and clamped to the coil tube

nearest to the LTHW flow connection. Note, maximum operating temperature of

95C

Electric heatingAll models, figure numbers 3, 4 and 6 only, can be fitted with a single phase, one

or two stage electric heating module, instead of the standard hot water heating

coil. The module includes electric element(s), power relay(s), high temperature cut-

out and miniature circuit breakers. Please refer to the Performance section of this

catalogue for outputs of models with electric heater modules.

Electronic speed control ESCAll models can be supplied with electronic speed control, instead of the standard

auto transformer. The ESC automatically varies the fan motor speed, air volume

flow rate and heat output (in the heating mode), in response to a change in

recirculation or room air temperature. On a rise in air temperature, the fan

gradually slows down and stops when the air temperature is 1K above the set-point.

A set-point adjustment knob and heating/cooling mode switch are provided. In the

cooling mode the operation is reversed to allow room air to be recirculated.

Air sensors can only be fitted within models 3, 5, 7, 0, , 3 and 5. Remote

sensors can be provided with all models.Electronic speed control is not suitable for use with:

a) models selected to introduce a constant quantity of outside or primary air.

b) ceiling mounting models, due to the risk of stratification, as the air volume flow

rate decreases and the leaving air temperature increases.

c) models with electric heater coil.

Special controlsVarious special control arrangements can be supplied to suit particular applications.

A 4V AC relay can be fitted, to allow a heater to be switched on/off remotely by a

controlled 4V AC supply.

4V AC relays can also be fitted, to allow master/slave operation of several fan

convectors from one pair of room thermostats. Please contact our local Agent/Sales Engineer for details.

Fitted plinthA 00mm or 50mm plinth, finished in black powder coating, can be fitted to all

floor and duct models, to raise the heater above the finished floor level.

Fitted isolating valvesDN0(3/4 BSP.) isolating ball valves or gate valves, can be provided fitted within

the casing.

Pencil proof loose grille and fixing framePencil proof loose grilles with fixing frames can be provided for use with heaters

which do not have fitted grilles. The fixing frame is intended for installation in

a wall opening, allowing the loose grille to be fixed to the frame with screws,

which are recessed between the grille blades. A loose grille has a natural anodised

surround and black powder coated grille core.

Loose grilles are unsuitable for external use. Proprietary weatherproof louvres are

recommended where outside air is to be introduced.

Special colours and finishesThe standard casing finish is powder coated flake grey, 0 A 03, BS4800.

As an option, heater casings can be supplied powder coated to a colour and finish

from our preferred range. A colour chart is available on request. Other BS 4800

and RAL colours are also available, subject to quantity. Please contact our local

Agent/Sales Engineer.

Note: when a special colour finish is applied to the casing, any fitted grilles and the back of

the heater will be finished standard black, unless otherwise specified.

The versatile range of standard

models (see page 4-5), each produced

in four casing lengths and with two

hot water coil types, allows Series AM

fan convectors to be used for many

applications, such as: Schools, Colleges,

Homes for Elderly People, Libraries,

Offices and Churches.

From the range of standard models,

it can be seen that there are models

suitable for floor, wall and ceiling

mounting within the room being

heated. Models 5, 3, 4 and 9 are

intended for installation in an adjacent

room. Where it is necessary to concealheaters within the building fabric or

ceiling void, we recommend our basic

uncased Series BM fan convectors.

Models 9, , 53 and 88 can be

used for heating, ventilating and free

cooling as they allow the introduction

of tempered primary or outside air

through the fan convector. These

models have a manually operated

damper but a motorised damper

can be fitted as an accessory, during

manufacture. If outside air is to be

introduced during the heating season,

the hot water coil must have frost

protection. Weatherproof louvres must

be supplied by others.

Care should be taken to ensure

heaters are sited so that there are noobstructions directly in front of them,

which could affect air circulation.

This is particularly important when

using reversed air flow models 37

and 4, and any model with electric

heating.

Ceiling mounted models 8, 30, 3 and

34 are generally less effective than floor

mounted models, since the entering air

temperature is higher at ceiling level

and the warm buoyant discharge air

may cause stratification and take longer

to produce comfortable conditions at

occupancy level. For these reasons,

we recommend floor or wall mounted

models, where the application allows.

Model 5 with optional plinth.

Application

General


11/36

a) From table , heat output 8.49kW , air volume flow rate 0 l/s, hydraulic

resistance .5 kPa

b) From table 3, heat output factor 0.50, hydraulic resistance factor 0.8.

c) Heat output 8.49kW x 0.50 = 4.5kW Hydraulic resistance .5kPa x 0.8

=0.35kPa

d) To estimate the leaving air temperature with the new output, find the

temperature rise t, and add it to the entering air temperature

t = = 16C + 18C = 34C

Refer to the range of standard

models (see page 4-5) to select the

model most suitable for the particular

application. From the calculated heat

loss and the operating conditions, the

quantity of heaters, heat output, figure

number and coil type can be selected,

using the Performance tables. If the

operating conditions are different to

those stated, use the appropriate factor

from table 3.For large rooms, it is usually better to

select two small heaters, rather than

one large one, to give better heat

distribution and lower spot noise levels.

Whenever possible, heaters should be

located near windows or in areas of

disproportionately high heat loss.

It is recommended that heaters are

selected to operate at medium speed

for general use or at low speed

for rooms where noise levels are

particularly important. Heaters should

only be selected at high speed for non

critical applications, such as entrancefoyers, corridors etc. or for initial rapid

warm up. Sound power levels are

available on request.

By design, Dunham-Bush fan

convectors have moderate leaving air

temperatures, low outlet velocities and

low air throws. Comfortable conditions

throughout the heated space are

achieved by good air circulation. It is

recommended that wherever possible,

the total volume of the room should

be circulated through the sum of the

heaters in the room, four to five times

per hour.
