Jotul GF 400 DV manual Gas Pressure, High Altitude Adjustment, Leak test, Pressure test points

A T-HANDLE GAS COCK IS REQUIRED IN MASSACHUSETTS TO COMPLY WITH CODE 248CMR.

Secure all joints tightly using appropriate tools and sealing compounds. For propane units be sure to use compounds that are propane resistant. Turn on gas supply and test for gas leaks using a soapy water solution. Never use an open flame to check for leaks.

Leak test:

1.Mix a 50-50 solution of water and dish soap.

2.Light appliance- see lighting instructions on the inside back cover of this manual or on the stove’s rating plate.

3.Brush or spray all joints and connections with the soapy water solution.

4.If bubbles appear at any connection or seam or a gas odor is detected, immedi- ately turn gas control knob to the OFF position.

5.Tighten or reconnect the leaking joint and retest for any gas leaks.

Gas Pressure

Correct gas pressure is essential for efficient and safe operation of the GF 400 DV Sebago gas stove. It is important that the correct pressure is established at the time of the installation. Proper gas pressure provides a consistent flow of gas to the appliance and is instrumental in checking for gas leaks.

Pressure Test: Attach a manometer to the appro- priate test point on the valve. See fig. 28. The gauge connections are located on the front of the valve under the On/Off/Pilot- knob. 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.)

ALWAYS TEST PRESSURES WITH VALVE CONTROL KNOB SET ON HIGH.

INLET GAS PRESSURES (inches water column)

	MIN	MAX
NATURAL GAS	5.0	7.0
PROPANE	12.0	14.9

The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing on that system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply 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 pressures of 1/2 psig (3.5 kPa).

MANIFOLD PRESSURES (inches water column)

	MIN	MAX
NATURAL GAS	1.2	3.8
PROPANE	2.9	11.0

High Altitude Adjustment

Installations located at altitudes from 2000 - 4500 ft. (610 m -1370 m) DO NOT require adjustment for alti- tude. DO NOT DERATE THIS APPLIANCE FOR ALTITUDE.
