The Laars Lite heater is also certified for installa- tion in an outdoor shelter in Canada when equipped with a drafthood. An outdoor shelter is an enclosure not normally occupied which does not communicate directly with occupied areas.
Check the rating plate on the heater for the correct Teledyne Laars part number. See instructions supplied with the drafthood for installation and attach- ment. When the draft hood is used, locate the heater so as to be in the same atmospheric pressure zone as the combustion air inlet to the heater.
If a drafthood is used, it must be connected to a vent pipe which stops at least 2 feet (0.61 meters [m]) above the highest point of the roof or other object that is within 10 feet (3.05 m) from the vent termination.
The vent pipe must have a listed vent cap which allows a full equivalent opening for flue products (see Figure 2).
