Section 5: Installing the gas line
Fuel Type
Verify that your fireplace is compatible with your available gas type.
Natural Gas or Propane shown by "N" or "L" in your model number on
rating plate. See instructions on converting to propane.
Gas Pressure
Optimum appliance performance requires proper input pressures.
Gas line sizing requirements will be determined in ANSI Z221.3 National
Fuel Gas Code in the USA and CAN/CGA B149 in Canada.
Pressure requirements (during operation):

Figure 17. D7215 Pressure Requirements
The manifold outlet pressure is set from the factory to the appropriate
pressure but should be verified.
To check pressures, use a manometer and a 1/8" rubber hose attached
to the inlet or manifold valve ports.
Only install gas shut-off valves approved for use by the state, province,
or other governing body in which the fireplace is being installed.

DANGER
After gas line is connected, each appliance connection, valve and
valve train MUST be checked while under normal operating pressure
with either a Liquid Solution, or Leak Detection Device, to locate any
source of leak. Tighten any areas where bubbling appears or a leak is
detected until bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks. A fire or explosion
will occur, causing serious injury, property damage or death.
NOTICE
When pressure testing the fireplace, Gas line, and input system
follow the appropriate local codes for your area. DO NOT connect the
fireplace to pressures in excess of 1/2 lb. This will damage the gas
control valve.

THE INFORMATION CONTAINED IN THIS DRAWING IS THE SOLE PROPERTY OF CANADIAN HEATING
Flexible gas connectors must not exceed 3 feet in length, unless allowable
within local regulations.
Connect incoming gas line to the 1/2" Male NPT gas inlet.
Purge all air out of gas line before connecting port.
Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
