Install Gas Supply Lines
A ½" (1.27 cm) gas supply connection is required as shown
below. To check system pressure, a plugged 1/8" NPT
tapping is required upstream of the manual gas shut-off
valve supplied with the heater.
Before connecting the heater to the supply system, verify
that all high pressure testing of the gas piping has been
completed.
DO NOT HIGH PRESSURE TEST THE GAS PIPING WITH THE
BURNER CONNECTED.
Follow these instructions to ensure a safe gas supply
system installation:
1. Support all gas piping with suitable pipe hanging
materials.
2. Use wrought iron or wrought steel pipe and malleable
iron fittings. The use of copper tube and brass fittings
is acceptable when such use is in compliance with local
codes. All pipe, tube, and fittings should be new and free
from defects. Carefully ream the pipe and tube ends to
remove obstructions and burrs.
3. Use LP-resistant joint compound on all threads.
4. Check the pipe and tube connections for leaks before
placing heating equipment into service. When checking
for gas leaks, use a soap and water solution; never use
an open flame.
5. The connector must be certified for use on a radiant
heater per "Standard for Connectors for Gas Appliances,
ANSI Z21.24 /CSA 6.10"

NOTE: A plugged 1/8" NPT tapping must be provided
upstream of the gas supply to the heater. The gas
supply line connecting to the heater appliance
should be such that it allows for some movement
of the unit. The appliance will go through
expansion and contraction during a heating cycle.
