10) Never operate the insert with the door open, or cracked slightly open, except briefly
during the lighting operation, and during refuelling. Leaving the door open continuously
could seriously overheat the chimney and adjacent combustibles. Do not operate the
insert if there is an abnormal air leakage into the unit, such as through deteriorated
gaskets or cracked or broken glass. Do not operate the insert without a door gasket.
Leakage can result in overheating, or in very airtight homes, could possibly cause
smoke spillage into the room. Smoke may contain carbon monoxide, which is
poisonous, and in sufficient quantities is a health hazard.
11) We recommend that you have a fresh air or make up air supply for the insert. In
Canada this is a building code requirement. If this is not done, it could cause poor air
quality in the home, poor and incomplete combustion, and poor efficiency in the insert.
Adequate ventilation is required to reduce effects from room air starvation and exhaust
fans.
Outside combustion air may be required if:
a.
The solid-fuel-fired appliance does not draw steadily, smoke rollout occurs, fuel
burns poorly, or back-drafts occur whether or not there is combustion present.
b.
Existing fuel-fired equipment in the house, such as fireplaces or other heating
appliances, smell, do not operate properly, suffer smoke roll-out when opened, or
back-draft whether or not there is combustion present.
c.
Opening a window slightly on a calm (windless) day alleviates any of the above
symptoms.
d.
The house is equipped with a well-sealed vapour barrier and tight fitting windows
and/or has any powered devices that exhaust house air.
e.
There is excessive condensation on windows in the winter.
f.
A ventilation system is installed in the house.
