The line must be disconnected from the gas sup-
ply line by closing the main supply manual gas shut-
off valve (gas cock) during any pressure testing of the
gas supply piping system that is equal to or exceeds
pressures of 1/2 psig (3.5 kPa).
6.4 Testing Gas Pressure
Proper gas pressure provides a consistent flow of
gas to the appliance and is instrumental in checking
for gas leaks. There are two pressure test points on
the front of the fireplace control valve where test
gauge connections are made. See Fig. 6.4. Gauge
connections are identified by:
• E for inlet or supply pressure ( the amount of gas
coming to the valve.)
• A for manifold pressure (the amount of gas that is
coming out of the valve to the burner.)
WARNING
DO NOT ALLOW THE INLET GAS PRESSURE TO
EXCEED
14.0
” WC (OR 1/2 PSIG) AS SERIOUS
DAMAGE TO THE VALVE MAY RESULT.
Inlet Pressure
MIN
MAX
Natural Gas: 5.0 WC (1.24 kPa) 7.0 WC (1.74 kPa)
Propane: 11.0 WC (2.74 kPa) 13.0 WC (3.24 kPa)
Manifold Pressure
MIN
MAX
Natural Gas: 1.6 WC (0.40 kPa) 3.5 WC (.87 kPa)
Propane: 6.4 WC (1.60 kPa) 10.0 WC (2.48 kPa)
ALWAYS TEST INLET PRESSURE WITH THE VALVE
REGULATOR CONTROL AT THE HIGHEST SETTING.
Symptoms of incorrect gas pressure include:
Insufficient gas pressure:
• Small pilot flame which can result in insufficient mil
-
livolts.
• Little variation in flame picture between HI and LO
regulator settings.
• Insufficient gas to support more than one appliance
causing nuisance outages or gas surges.
Excessive gas pressure:
• Permanent damage to valve causing complete appli
-
ance shut down.
• Too large a pilot flame excessive fuel consumption in
standing pilot mode (CPI).
• Sooting due to impingement and/or incorrect fuel to
air mix.

6.5 Fuel Conversion
The GZ 455 DV is shipped from the factory equipped to
burn NATURAL GAS only. If PROPANE gas is to be used
as fuel, the appliance must first be converted for using
Propane Conversion Kit 157409 included with the stove.
Use NG Conversion Kit 157408 to change back for use with
natural gas.
