GAS LINE INSTALLATION
Consult all local codes. All gas piping must be installed to comply with local codes, or in the absence of local codes, with
the latest edition of the National Fuel Gas Code ANSI Z223.1/NFPA54.
Remove the baseplate for ease of gas line installation. Remove three (3) screws along the front edge of the baseplate.
Remove four (4) screws which secure the baseplate to the combustion casing (two at rear and one along each side).
Replace baseplate prior to connecting gas line to heater. Consult heater installation and operating instructions for correct
installation of the heater into the fi rebox.
The

" NPT pressure tapping point must be installed
upstream of the heater.
A sediment trap may be upstream of the heater to prevent moisture and contaminants from passing through trap to the heater
controls and burners. Failure to do so could prevent the heater from operating reliably. Consult applicable codes.
An external regulator must be used on all propane / L.P.G. heaters, in addition to the regulator fi tted to the heater,
to reduce the supply tank pressure to 13" w.c. (maximum). Any copper tubing used to supply propane / L.P.G. from
the tank must be internally tinned.
Note: When connecting propane / L.P.G. vent-free room heaters, you must use pipe sealant resistant
to propane / L.P.G.
Important: Hold heater regulator with a wrench to prevent movement when connecting to inlet piping.
Check gas type: The gas supply must be the same as stated on the heater’s rating plate. If the gas supply
is different, DO NOT INSTALL THE HEATER. Contact your dealer for the correct model.
After completing connection, test all gas joints from the gas meter to the gas heater regulator for leaks. Using soap and
water solution or a gas sniffer. DO NOT USE AN OPEN FLAME.
Plumbing connections should only be performed by a qualifi ed, licensed plumber.
Main gas supply must be off when plumbing gas line to fi replace or performing
