Natural Draft Applications
Natural Draft Applications - All Caprice models are certified as Natural Draft boilers
which require a “Chimney System”. The exhaust gases must be vented directly to the
chimney. Failure to follow these instructions will result in serious injury or death.
Blocked Vent Switch - All Natural Draft Caprice boilers require a Blocked Vent Switch
which is factory supplied and packaged with the burner kit and is mandatory in Canada.
The Block Vent Switch must be field installed as per the instructions in this manual and the manufacturers
instructions included with the switch. Failure to follow the specified instructions may result in fire, property
damage, personal injury, or death.
