1-2 SPECIAL FEATURES
AUTOMATIC IGNITIONMEMORY BACK UP: Set memory can be kept in
case of power failure for up to 5 minutes.DUAL BLOWERS: Separate fans for combustion
and room air circulation.THERMOSTATICALLY CONTROLLED: Adjusts to
the desired room temperature.BUILT-IN TIMER: Heater will automatically
operate as programmed by the user.AUTOMATIC RESET AFTER POWER FAILURE:
Heater will automatically resume operationafter power is restored.
INDICATOR LIGHTS: Easy-to-see signals showwhen heater is in operation, when timer isactivated, and when the burner is operating inlow or high modes.
CLEAN OPERATION: Products of combustion arevented outside.
CONSUMES NO ROOM AIR: Air for combustionis drawn from outside.
EASY INSTALLATION: Includes all parts requiredfor standard installation
1-3 SAFETY FEATURES
SAFE RE-LIGHTING: Heater will not restart untilits combustion chamber has cooled.
ELECTRICAL PROTECTION: Heater automaticallyshuts off in the unlikely event of a malfunction inthe electrical circuitry or disruption of the powersupply.
NO EXHAUST IN ROOM: Products of combustionare discharged outdoors.
FLUE PIPE: Outside air is drawn through a pipe-within-a-pipe venting system. This processpreheats combustion air and regains heat fromexhaust gases.
A CAUTION: ALTERNATE POWER SOURCESThe Monitor GF200 may not operate whenpowered by sources such as an auxiliarygenerator, UPS (Uninterrupted PowerSource), inverters, etc.This unit may not operate on a GFI (GroundFault Interrupter) power circuit.Check with your dealer for guidance onspecific applications.
MONITOR HEATING SYSTEMSection 1: Description
1-4 MANUAL GAS VALVEThe Manual Gas Valve is included with Heater.Connect the Manual Gas Valve to gas inlet at rearof the cabinet.Connection must be checked for gas-tightnessby means of leak detector solution, soap andwater, or an equivalent nonflammable solution, asapplicable.
Figure 1 -1
1-5 AUTOMATIC GAS VALVEThe Automatic Gas Valve is a normally closedtwo-stage, electro/mechanical device whicheither allows gas to flow to the burner or preventsit from doing so.When the valve is energized, a spring-loadedplunger is lifted to permit the flow of gas.Removing power from the valve drops theplunger down into the inlet to prevent gas frompassing through.

MONITOR HEATING SYSTEMSection 1: Description
1-11 FLAME DETECTORAn Electrode which detects that the burner hasbeen ignited, using the flame as a conductor,instantaneously detects when the flameextinguishes and shuts down the AutomaticValve.
1-12 COMBUSTION BLOWERThe Combustion Blower has a two stage intakefan. The intake fan draws in outside air thru theflue pipe for internal combustion.Burner modes control fan speeds and theSolenoid Damper in the Blower Casing. Thosefunctions are as follows:
COMBUSTION AIR CONTROLBurn Mode Fan Speed Solenoid Damper
High High Off (open)Low Low On (close)
Setting air flow for Solenoid Damper on Lowmode should read 5.5±0.5mmHzO for Nat.and 5.5±0.5mmH2O for LP.
1-13 HEAT EXCHANGERAn inlet at the top of the Heat Exchanger permitsthe heated air to travel from the CombustionChamber into the Heat Exchanger.An outlet, at the bottom of the Heat Exchanger,permits combustion by-products to be vented tothe Flue Pipe.While moving through the Heat Exchanger, thehot air within the Heat Exchanger heats theoutside metal walls. The hot metal walls, in turn,heat air that is pushed past the Heat Exchangerand is circulated into the room. An air baffle,directly in front of the Heat Exchanger, deflectsthe heated air downwards, and out, through theLouver assembly.
1-14 FLUE PIPEFlue Pipes are available in three (3) sizes. Thisprovides the flexibility to meet the installationrequirements for dwelling of various wallthicknesses. One side of the Flue Pipe containsa "T"-shaped fitting consisting of four ports. Thisside is mounted on the interior wall of thedwelling. The pipe side of the Flue Pipe is ventedoutside the dwelling. The Flue Pipe assemblyconsists of two concentric tubes. Outside air isdrawn through the cylindrical space between thetubes.As the cool air enters, it is heated by the hot airthat is exiting the system.A large-bore, flexible hose connects the air inletport on the Flue Pipe with the Combustion
Blower; a cloth-covered metal pipe connects theHeat Exchanger with the exhaust outlet on theFlue Pipe.
1-15 AIR CIRCULATION FANThe Circulation Fan is driven by a two speedmotor and is designed to circulate the heatedroom air. If the heater is running in low burnmode, the fan also runs at low-speed; in highburn mode, the fan advances to high-speed.Operation of the fan is controlled by theMicroprocessor and Fan Thermostat Switch.Physically assembled with a protective wirecage, the entire fan assembly is secured to abracket on the rear of the Heater Cabinet. Asheet metal conduit, at the rear of the Heater,protects the fan wiring from damage.
MONITOR HEATING SYSTEMSection 1: Description
1-16 AIR PRESSURE SWITCHThis switch consists of a rubber diaphragm whichsenses changes in air pressure (it is connected tothe Combustion Blower and the CombustionChamber) and a normally-open, micro switch.Should an abnormal pressure differential exist,the switch opens to disable the circuitry thatcontrols the supply of gas. Since the flow of gasto the Burner is cut off, the flame extinguishes,and the burner Status Indicators blink.This safety mechanism can be triggered byseveral conditions:
- Leak, loose, or broken tubing which connectsthe Air Pressure Switch with the CombustionBlower or the Combustion Chamber
- Clogged or blocked Air Line- Blocked or clogged Flue Pipe-Intake port of the Combustion Blower is
blocked- Combustion Blower is inoperable
1-17 OVERHEAT PROTECTOR SWITCHThe normally-closed Overheat Protector Switchsafeguards the heaters against damage due tooverheating.The Switch is rated 110°C (230° F). Should aMonitor overheat (internal temperatures risebeyond 110°C/230°F) the switch will open to shutdown the heater. After extinguishing the flame, theBurner Status indicators continue to blink. TheOverheat Protector Switch will automatically resetafter cooling down. Once the heater has cooled to90°C(194°F), the system can be restarted. Torestart the Monitor, proceed as follows:A. Press ON/OFF Switch to OFF.B. Allow heater to cool.C. Troubleshoot the cause of the overheat.D. Press ON/OFF switch to ON.E. Proceed with normal operation.
1-18 THERMAL FUSEShould the Overheat Protector Switch malfunction,and the heater be further overheated, the thermalfuse(internal temperatures rise beyond 1673C/333°F) melts and prevent further overheating.
1-19 OVERCURRENT FUSE2-amp., 125VAC, fuse protects the heater fromdamage resulting from power overloads. In theevent of a power surge or internal wiring hazards,the fuse opens and power to the heater is cut off.
1-20 ELECTRICAL SYSTEMElectrical power is supplied to the Monitor to runthe Microprocessor and the other electrically-energized component.
Electrical operation of the Monitor can be thoughtof as having the following eight(8) distinctphases: plug in; turn on; pre-purge; ignition; pre-combustion; heating; shutdown and post-purge.
1-21 MICROPROCESSORPrincipally consisting of a 64-pin IntegratedCircuit, the Microprocessor provides safetytimings, controls relays and provides clock andthermostat functions for the Monitor heater.
1-22 TEMPERATURE SENSORThe sensor which is capable of sensing roomtemperature within a range of 42°F to 96°F, canbe left mounted on the back of the heater cabinetor be wall mounted.
Approximately 61/2' (about 200 cm) of No. 20AWG Wire is supplied with the sensor to facilitatewall mounting the sensor in a favorable location.
I-23 SAFETY MECHANISMSSeveral safety mechanisms have been built intothe Monitor Heating System. These devicesprotect the user against personal injury, protectthe heater against damage, and shutdown theheater if a malfunction occurs.
1-24 CLOTH COVERED EXHAUST PIPEInsulating cloth covers are to be placed over allmetal surfaces of the Exhaust Line duringinstallation. Since combustion by-products arevented at elevated temperatures, the ExhaustPipe will become hot during operation. Theinsulating cloth covers protect the user from burnhazards associated with accidental contact withthese heated metal surfaces. During installationmake sure that all Exhaust Lines are tight. Do notoperate the heater without the insulating covers.
1-25 AIR CIRCULATION FAN GUARDThis guard is an integral part of the fan assembly.The guard protects the user against physicalinjury which could occur from accidental contactwith revolving metal fan blade.
1 -26 SLIDE SELECTOR FOR THE RESET TEMP.Once power is restored after power interruptionby power failure or by disconnecting heater plugfrom wall outlet, heater will resume operation inthe MANUAL mode and maintain roomtemperature according to the setting temperatureselected by using the selector for the resettemperature at the lower right hand side of thecabinet.
