Gas Line Installation
! The gas line must be installed in accordance with all local codes, if any; if not, follow
current ANSI Z223.1 or NFPA 54 in the USA and the current CGA B149 in Canada.
! The heater and gas control valve must be disconnected from the gas supply piping during
any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPA). For
pressures under 1/2 psig (3.45 kPA), isolate the gas supply piping by closing the manual
shutoff valve.
• This heater is designed for natural gas but can be converted to propane. Check the
sticker on top of the gas control valve to verify the correct fuel is used (see page 4).
• Leak test all gas line joints and the gas control valve prior to and after starting the heater.
• The gas inlet accepts a 3/8” F.P.T. Fitting
• The location of the gas inlet is shown below
• A manual shutoff valve is required for installation (it must be located within 3’ of the
heater). T-Handle gas cocks are required by Massachusetts in compliance with code 248
CMR.

Gas Inlet Pressure
• With the heater off, the inlet pressure must meet the requirements listed in the table
below
? If the pressure is not sufficient, make sure the piping used is large enough and the total
gas load for the residence does not exceed the amount supplied.
? The supply regulator (the regulator that attaches directly to the residence inlet or to the
propane tank) should supply gas at the suggested input pressure listed below. Contact
the local gas supplier if the regulator is at an improper pressure.
Standard Input Pressure
Natural Gas 7” W.C. (1.74 Kpa)
Propane 13” W.C. (2.73 Kpa)
