Enviro C-11102, C-11253, 50-1472 owner manual To Test Valve Pressures, Labeled Gas Valve

Initial Installation

QUALIFIED INSTALLERS ONLY

•A shut-off valve is not supplied with this unit but one should be installed.

•The appliance and its shut-off valves must be disconnected from the gas supply piping system during any pressure testing where the pressure exceeds 1⁄2 psig (3.45 KPa) or the valve will be damaged.

•The unit must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at pressures equal to or less than 1⁄2 psig (3.45 KPa).

TO TEST VALVE PRESSURES:

The pressure taps are located on the front side of the valve (see Figure 51 & 52).

1.Follow steps 1-4 in REMOVING VALVE COVER - MAINTENANCE

AND SERVICE. to access the valve.

2.	Turn set screw one (1) turn counter-clockwise to loosen.
3.	Place 5/16 in (8 mm) I.D. hose over the pressure taps.
4.	Check pressures using a manometer.
5.	When finished, release pressure, remove hose and tighten
	set screw.
		Figure 51: Labeled Gas Valve.
6.	Re-install the valve cover, burner tray, brick panels (refer to
	SECONDARY INSTALLATION - INSTALLING THE BRICK PANELS), log
	set and ember material (refer to SECONDARY INSTALLATION -
	LOG SET AND EMBER INSTALLATION) and the glass door.

Always check for gas leaks with a soap and water solution after completing the required pressure test.

NEVER USE AN OPEN FLAME FOR

LEAK TESTING.
