VENTING

This is a vented appliance and must be connected to a chimney in accordance with the current installation codes. In absence of local codes, install to the current National Fuel Gas Code, ANSI Z223.1, or the current CAN/CGA B149, Installation Codes. This model can be common-vented.

A minimum six inch diameter (6"ø) B-vent or class A vent is required. A minimum 10' vent height is required. Secure the B-vent to the exhaust collar on the stove top with 3 screws. In cold climates, the use of a B-vent and an insu-

lated chase is recommended.

This thermally activated switch, located in front of the draft hood, senses an increase in temperature and acts as a safety shut-off (See 'A' below). It shuts down the gas to the main burner in the event of a severe downdraft of air or a blocked or disconnected chimney flue. If the flue is blocked or has no "draw", the safety switch will automatically shut off the supply of gas to the main burner within 10 minutes.

HIGH LIMIT SWITCH

This thermally activated switch, located in front of the draft hood, senses an increase in temperature and acts as a safety shut-off (See 'A' below). It shuts down the gas to the main burner in the unlikely event of the unit overheating.

The HI Limit switch will automatically reset after the unit

1.Close all doors and windows in the room / start ex- haust fans in the home / turn the fireplace blower off (if so equipped).

2.Set controls to "high" and light the unit.

3.Wait 5 minutes. Light a match and hold to the front of the draft hood. FIGURES 4 & 5.

FIGURE 4

Venting action is satisfactory, if smoke and flames are drawn into the draft hood.

FIGURE 5

Venting action is unsatisfactory, if the smoke spills back, and the flame splays outward. If venting action is unsatisfac- tory, turn off the unit, wait 10 minutes and try again. If the smoke is still not drawn into the draft hood, turn the unit off and check for vent blockage or restriction. If necessary, consult with a quali- fied inspector.

The Vent Safety or Hi Limit switches must not be adjusted or disabled.

In the event that either switch or any associated parts are exchanged, only original manufacturer's parts may be used.
