Venting; Vent Safety Switch; Hi Limit Switch; Venting Action Check - Napoleon BGNV42N Installation And Operation Instructions Manual

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 insulated chase is recommended.

VENT SAFETY 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 event of a
severe downdraft of air or a blocked or disconnected chimney fl ue. If
the fl ue is blocked or has no "draw", the safety switch will automatically
shut off the supply of gas to the main burner within 10 minutes.
This switch must be manually reset by depressing the plunger.
Refer to Figure 2.
Tampering with the safety switch can result in carbon monoxide
poisoning and possible death.

event of the unit overheating. The HI Limit switch will automatically
reset after the unit has cooled down, resuming gas fl ow to the main
burner.

VENTING

A test for correct venting action must be made before the in-
stalled unit can be left with the customer.
Follow the procedure below:
1. Close all doors and windows in the room / start exhaust fans in the
home / turn the fi replace 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.
Venting action is satisfactory, if smoke and fl ames are drawn into
the draft hood.

HI LIMIT
SWITCH
Venting action is unsatisfactory, if the smoke spills back, and the
fl ame splays outward. If venting action is unsatisfactory, 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 qualifi ed 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 ex-
changed, only original manufacturer's parts must be used.
