STEP 3 - LOCATE THERMOSTAT 1 . Thermostat must he installed in same room as heater . 2 . Locate thermostat on an inside wall approximately 5 feet [ 153 cm } above the floor and at least 6 feet [ 183 cm } from the heater . 3 . Do not locate thermostat so as to be effected by heat from sources other than the heater ( i . e . direct sunlight , lamps , T . V . sets , radiators , registers , etc . ) . 4 . Do not locate thermostat in unusually cool locations ( i . e . outside wall , on a wall separating the heated area from an unheated area , in drafts from stairwells , doors , windows , etc . ) . 5 . Install thermostat where there is good air circulation and where it is readily accessible tbr wiring , service and adjustment . Never install in a comer , alcove , over or behind furniture or behind a door . STEP 4 - GAS SUPPLY ROUGH - IN 1 . An inch and a half ( 1 - 1 / 2 " ) opening is provided toward the right front of the liner bottom tbr installation of the gas supply line . This opening facilitates installation of a gas supply line located inside the room where the heater is installed . If the gas supply line is located in a stud space or other concealed area consult the gas supplier , local code officials or the latest edition of ANSI Z223 . 1 / NFPA 54 for special instructions and approval for a concealed gas supply line . NOTE : If gas supply line is concealed , it must be brought into the room under the heater as there must be a manual shut - off valve installed in the gas supply line that is accessible from inside the room where the heater is installed . 2 . The valve must be connected only by means of a pipe union of the ground joint type . 3 . Mr . Installer , support gas valve , with a second wrench , when connecting the gas supply line , to prevent damage . 4 . Install at least 3 / 8 " gas supply line . Contact local gas supplier if any questions . 5 . Install a drip leg in gas supply line immediately upstream from the gas connection to heater . ( see local codes ) , and provide a 1 / 8 " N . RT . plugged tapping , accessible for test gauge connection and an indi - vidual manual shut offvalve accessible within room where heater is installed . ( See Figure 4 ) . The heater and its individual shut offvalve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1 / 2 psig ( 3.5Pa ) . The heater must be isolated from the gas supply piping system by closing its individual manual shut offvalve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1 / 2 psig ( 3.5Pa ) . 6 . Test all connections for leaks using a soapy solution . NEVER USE AN OPEN FLAME TO TEST FOR LEAKS . 7 . The maximum inlet gas supply pressure for natural or L . R / Propane gas is 1 / 2 p . s . i , or 14 " w . c . 8 . The minimum inlet gas supply pressure for the purpose of adjustment is 4.5 " w . c . for natural gas or 11.0 " w . c . for L . R / Propane gas . GAS SUPPLY THROUGH GAS SUPPLY FROM GAS SUPPLY OUTSIDE WALL CRAWL SPACE INSIDE ROOM WITH HEATER Outside Wall . . . . . . .

MAINTENANCE INSTRUCTIONS For correct and safe operation , keep heater and heater area clean . At regular intervals , turn control valve to OFF , let heater cool and clean inside control and heat exchanger colnpartments . To clean outside cover , use a dmnp cloth , do not use any kind of solvent or cleaning fluid as they may leave a residue that could burn or give offodors when heater is turned on . Have heater , including exhaust / intake tubes , checked , cleaned and ! or repaired by a qualified service person prior to use each year . Follow a regular service and maintenance schedule for safe and efficient operation . Do not obstruct combustion , ventilation or circulating air . Do not place furniture in front of heater . Keep bushes , shrubs , etc . trimmed to maintain a 12 " clearance below and 48 " from back of heater . If any components are removed , make sure all gaskets are reinstalled and are in good condition . If any sign of damage , replace gasket as this is a sealed system and must be air - tight for proper operation . DO NOT operate heater with any gasket missing or damaged . Failure to replace a missing or damaged gasket may result in property damage , personal in ) ury , loss of life , or poor performance .
