Gas Pressure - Jøtul GI 350 DV Scan 65i Installation And Operation Instructions Manual

Soap Solution Leak Test
• Mix a 50-50 solution of water and dish soap.
• Light appliance- see lighting instructions on page
23 of this manual or on the fireplace's rating plate.
• Brush or spray all joints and connections with the
soapy water solution.
• If bubbles appear at any connection or seam or a
gas odor is detected, immediately turn gas control
knob to the OFF position.
Tighten or reconnect the leaking joint and retest
for any gas leaks.

Gas pressure

Proper gas pressure provides a consistent flow of
gas to the appliance and is instrumental in checking
for gas leaks. The gas control valve on the fireplace is
equipped with pressure test
points for gauge connections.
The gauge connections are
located on the front of the
valve next to the On/Off/Pi-
lot knob. Gauge connections
are identified by:
• IN / E for inlet or supply
pressure (the amount of
gas coming to the valve.)
• OUT / A for manifold pres-
sure (the amount of gas
that is coming out of the
valve to the burner.)

the valve.

The appliance must be isolated from the gas sup-
ply line by closing its individual manual gas shut-off
valve (gas cock) during any pressure testing of the gas
supply piping system that is equal to or exceeds pres-
sures of 1/2 psig (3.5 kPa).
Inlet pressure
MIN.
Natural Gas: 5.0 WC (1.24 kPa)
Propane: 12.0 WC (2.98 kPa)
Manifold pressure
MIN.
Natural Gas: 1.2 WC (0.29 kPa)
Propane: 2.9 WC (0.72 kPa)
ALWAYS TEST PRESSURE WITH VALVE CONTROL KNOB
SET ON HIGH. Symptoms of incorrect gas pressure
include:
Insufficient gas pressure:
• Small pilot flame which can result in insufficient
millivolts.
• Little variation in flame picture between HI and LO
settings.
• Insufficient gas to support more than one appli-
ance causing nuisance outages or gas surges.
Excessive gas pressure:
• Permanent damage to valve causing complete ap-
pliance shut down.
• Too large a pilot flame resulting in overheating of
the power generator and consequent shut down.
• Sooting due to impingement and/or incorrect fuel
to air mix.
High Altitude Adjustment
Installations located at altitudes from 2000 - 4250 ft.
(610 M - 1370 M), DO NOT require adjustment. Do not
derate this appliance for altitude.
