Jotul GF 400 DV Gas Supply Connection, Pilot orifice removal and replacement, Regulator assembly

14.Remove the Regulator Tower, Gasket, white plastic disk, and Spring.

15.Install the new regulator: Be sure the new gasket is properly positioned and tighten screws securely.

16.Install the identification labels to the stove so that they can be seen by any person that may be servicing the stove. Label A: apply to back of stove.

Label B: apply to stove’s rating plate.

Small valve Label: apply to valve.

17.Reassemble the stove, apply gas to the system and check for leaks using a soapy water solution.

18.Adjust the Air Shutter:

CAUTION! USE WORKGLOVES. SURFACES MAY BE HOT!

You will need to adjust the shutter to the position that supplies the correct amount of air mixture to achieve the best flame picture with your particular installation. Start with the shutter stem at the midway position in the slot in the bottom of the stove. See fig. 21. Pushing the stem back will restrict air, while pushing it forward will open the shutter. Too much air will produce a lighter flame, while too little will promote long, dark flames and may pro- mote sooting. Make adjustments in small incre- ments. With some experimentation, you will find the shutter position that works best for your installation.

NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

Correct gas pressure is essential for efficient and safe operation of this appliance. Correct gas pressure must be established at the time of installation. For more details, see the Gas Pressure section of this manual (page 19).

ALWAYS REFER TO THE LIGHTING INSTRUCTIONS ON THE INSIDE BACK COVER OF THIS MANUAL WHEN LIGHT- ING YOUR STOVE.

Gas Supply Connection

Connect the gas supply line to the stove, before installing the optional Blower.

If the blower will be installed, use a 45° elbow off the control valve to create clearance required for the blower installation.

The gas supply line connection is made to the left side of the valve. The gas supply line should be 3/8" npt with a 1/2" diameter supply, or the appropriate size to provide sufficient gas pressure to the valve regardless of the input setting.

The use of Flexible Gas Appliance Connectors is acceptable in many areas in the U.S. However, Canadian methods vary depending on local code.

ALL INSTALLATIONS MUST COMPLY WITH LOCAL CODE OR IN THE ABSENCE OF LOCAL CODE, MUST COMPLY WITH THE MOST RECENT EDITION OF THE NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR CAN-B149.

All codes require a gas shut-off valve (gas cock) and union, to be installed in the supply line, and in the same room as the appliance. This allows for the disconnection of the stove for servicing and maintenance. See fig. 27.
