• 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 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
psig (3.45 KPa).

Initial Installation
QUALIFIED INSTALLERS ONLY
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 R

ND 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 nished, release pressure, remove hose and tighten
set screw.
6. Re-install the valve cover, burner tray, brick panels (refer to
S
ECONDARY INSTALLATION - INSTALLING THE BRICK PANELS), log
set and ember material (refer to S

OG 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.
