Connect the Gas Supply Line
Check the Rating Plate attached by a steel cable to the firebox, to confirm that you have the appropriate firebox for the type of fuel to be used.
This appliance should only be connected by a qualified gas technician. Test to confirm manifold pressures as specified below.
The Jefferson Heater and its individual shutoff valve must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).
The Jefferson Heater 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 pressure equal to or less than 1/2 psig.
There must be a gas shutoff between the stove and the supply.
In order to connect Natural Gas, use a fitting with 3/8” NPT nipple on the valve side and 1/2” natural gas supply line with an input of 28,000 BTUs at a manifold pressure of 3.5” and minimum inlet supply for adjustment of 5.5” W.C.
In order to connect Propane, use a fitting with 3/8” NPT nipple on the valve side and 1/2” propane gas supply line with an input of 28,000 BTUs at a mani- fold pressure of 11.0” and minimum inlet supply for adjustment of 11.0” W.C.
Gas connection should be made in accordance with current National Fuel Gas Code, ANSI Z223.1. Since some municipalities have additional local codes, be sure to consult you local authority.
Connect the gas supply and test for leaks. Use a 50/50 solution of liquid soap and water to test for leaks at gas fittings and joints. NEVER test with an open flame.
Light the pilot according to the directions on page 14, before going to the next step.
Install the Log Set
1.Remove the logs from their packaging, and inspect each piece for damage. DO NOT INSTALL DAM-
AGED LOGS.
2.Install the rear log 1 by centering it side to side on the sheet metal shelf at the back of the firebox. (Fig. 14)
3. Install the left 2 and right 3 middle logs by engaging holes on their bottoms with pins on the burner brackets. (Fig. 14)
4.Loosely sprinkle the lava rocks directly on top of the burner between the decorative grate and the middle logs. Do not place any ember material behind the middle logs. (Fig. 15)
5. Engage the upper log 4 with the right middle log as
shown in Figure 15. Swing the top end toward the rear of the firebox and rest on notch on top of rear log. (Note: This log will touch the back of the firebox.) Engage the top log 5 with the upper log and the left middle log. (Fig. 15)
