5. PIPING REQUIREMENTS
All­piping­installed­must­comply­with­local­codes­and­ordinances­
or­with­the­National­Fuel­Gas­Code,­ANSI­Z223.1­(NFPA­54),­
whichever­takes­precedence.­When­installing­piping,­the­following­
requirements­must­be­taken­into­consideration:
•­ Use­new­properly­reamed­black­pipe­free­from­chips.
•­ Apply­a­good­quality­pipe­compound­to­all­male­threads­prior­
to­assembly.­If­L.P.­gas­is­the­fuel,­ensure­that­pipe­compound­
is­resistant­to­L.P.­gas.­DO­NOT­USE­TEFLON­™­tape.
•­ Prior­to­installation,­apply­pipe­compound­to­all­male­threads­
as­shown­in­Figure­1.

6. GAS PRESSURE
When­a­higher­than­the­maximum­recommended­gas­pressure­is­
being­maintained­at­the­main­gas­line,­a­separate­regulator­must­
be­installed­ahead­of­the­heater.­Refer­to­Table­1­on­page­3­for­
maximum­allowable­pressure­for­stated­heater­model­and­gas.
See­heater­rating­plate­for­minimum­gas­supply­pressure­“For­the­
Purpose­of­Input­Adjustment.”

7. ELECTRICAL
NEVER­CONNECT­POWERPILE­GAS­VALVE­OR­THERMOSTAT­TO­
LINE­VOLTAGE­OR­A­TRANSFORMER.
8. THERMOSTAT & LOCATION
Make­sure­that­the­electrical­characteristics­of­the­thermostat­
match­those­of­the­heater­controls.­For­best­results­thermostat­
should­be­positioned­5­ft.­above­floor­where­air­can­circulate­
freely­around­it.­
DO NOT MOUNT directly to cold-side wall, in
direct drafts, or directly beneath the infra-red heater.
Ensure­that­the­selected­thermostat­location­meets­all­of­the­
above­requirements.­Refer­to­the­instructions­that­come­with­
the­thermostat­for­additional­general­information­and­mounting­
instructions.
If­the­wall­is­of­stud­and­wallboard­construction,­then­use­the­#6­
by­1­inch­sheet­metal­screws,­included­with­the­thermostat,­and­
mount­the­thermostat­in­the­selected­location.
If­wall­is­brick­or­masonry,­the­appropriate­anchors­must­be­
obtained­to­accommodate­the­thermostat­mounting­screws.­Use­
the­back­plate­of­the­thermostat­as­a­template­to­mark­the­hole­
location,­drill­appropriate­size­anchor­holes,­install­the­anchors­and­
securely­attach­the­thermostat­using­the­mounting­screws.
Connect­the­thermostat­wires­to­gas­valve­as­shown­in­Figure­4.
