DIRECT VENT MODEL:

WARNING: This appliance has been designed to draw room air for proper heat circulation from the sides and bottom of the unit, and out the top front. Blocking or modifying these openings in any way can create hazardous situations.

The vent height for the Sonnet must be between 10ft (3.05) and 35ft (10.67m).

This model is vented with a 2” intake and a 3” exhaust aluminum or stainless steel flex vent leading into a co-linear to co-axial vent adaptor and using a vertical termination cap. The flue collars of this model will fit inside of a standard 2” or 3” vent and may be fastened directly to the vent. The exhaust vent is on the top of the flue connector. The air intake is on the angled back of the vent collar plate. The air intake can be increased to a standard 3” size using Adaptor (50-1499 - 2” to 3” Air Intake) included with this unit.

Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been properly sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must be installed in the correct locations on the back of the Sonnet.
