8. GAS LINE CONNECTION AND TESTING
WARNING: Only persons licensed to work with gas piping can make the gas connections to this appliance.
This appliance is equipped with a 3/8” stainless steel flex line from the valve. This line may be routed through the hole in the rear
of the pedestal, or on inserts, routed through the fire box sides. An adapter plate is available for installations that do not allow flex
pipe through cabinetry.
NOTE: Consult your local authorities and in CAN. the CAN/CGA-B149 (1 or 2) Installation Code, For USA gas installations follow
either local codes or the current edition of the National Fuel Gas Code ANSI. Z223.1.
The appliance and its shutoff 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 damage will occur to the valve.
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
Always check for gas leaks with a soap and water solution or an approved manner after completing required pressure
tests.
ORIFICE SIZES, PRESSURES AND BTU'S
The efficiency rating of this appliance is a product thermal efficiency rating determined under continuous operating conditions and
was determined independently of any installed system. All models are equipped with a variable output gas control.

TO TEST VALVE PRESSURES
-Turn set screw counter clockwise to loosen, 2 turns.
-Place 5/16" I.D. hose over pressure tap system.
-When finished, release pressure, remove hose & tighten set
screw.
EUROSIT VALVE:
The pressure taps are located through the left side of the
pedestal on the left side of the valve
(Rear - inlet pressure, Front - manifold pressure).
NOVASIT VALVE:
The pressure taps are located on the front of the valve
through the control panel.
(Left - manifold pressure, Right - inlet pressure).
NEVER USE AN OPEN FLAME FOR LEAK TESTING.
