Inspecting the Venting System

This appliance venting system was designed and con- structed to develop a positive flow adequate to remove flue gases to the outside atmosphere.

Any foreign objects in the venting system, except those designed specifically for the venting system, may cause spillage of flue gases.

To inspect the venting heat exchanger system, make sure the main gas valve is off. Remove window frame assembly. (Refer to Window Frame Assembly Removal section) Using a flashlight, check the area above the baffle in the combustion dome. Clean if necessary.

Inspecting the Venting/Heating

Exchange System

Any foreign objects or corrosion in the heat exchanger or venting system may cause spillage or leakage of the gases into the living space.

Ceramic Refractory Installation

1.Remove window frame assembly and logs.

2.Place refractory side supports so that the hole fits over the screw head on the firebox floor.

3.Place refractory base sides on the floor of the fire- box.

4.Attach adjustable tabs, packed with refractory, onto the studs found on the top of the firebox using the 2-10/24 nuts provided.

5.Place back refractory - small brick edge down into support and swing into position. (Fig. 41)

6.Slide side panels into side supports and behind side tab and adjust, fitting the ceramic tight to the side of the firebox. Tighten nuts. (Fig. 42)

Mortar lines must be aligned.
