Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.	Disconnect appliance with its appliance
	main gas valve (control valve) and equip-
	ment shutoff valve from gas supply pip-
	ing system. Pressures in excess of 1/2
	psig will damage fireplace gas regulator.
2.	Cap off open end of gas pipe where
	equipment shutoff valve was connected.
3.	Pressurize supply piping system by ei-
	ther using compressed air or opening
	main gas valve located on or near gas

	system. Apply mixture of liquid soap
	and water to gas joints. Bubbles form-
	ing show a leak.
5.	Correct all leaks at once.

3.Check all joints from gas meter to equip- ment shutoff valve (see Figure 27). Ap- ply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

CONVENTIONAL FIREPLACE INSTALLATION

Conventional installation of fireplace involves installing fireplace along with corner, face, or cabinet mantel with hearth base accesso- ries against a wall in your home. Follow instructions below to install fireplace in this manner.

Note: The instructions below show installa- tion using the cabinet mantel and hearth base accessories (see Accessories, page 34). The hearth base accessory shown is optional for this installation. You can install fire- place and cabinet mantel directly on the floor. The corner mantel accessory cannot be installed with the hearth bases. You must install corner mantel directly on the floor.

1.Assemble cabinet mantel, hearth base, and trim accessories. Assembly instruc- tions are included with each accessory.

2.When installing blower, install a prop- erly grounded, 120 volt three-prong electrical outlet at fireplace location if an outlet is not there. If possible, lo- cate outlet so cabinet mantel will cover it when installed (see Figure 28).
