Note N/A Indicates model equipped with "Wayne" burner.

A clearance of 24 inches is recommended from serviceable parts such as relief valve, power burner, drain valve and anodes (anodes are located on side above cold water inlet).

BTP models are Category I appliances (Fan Assisted) and require a negative draft. These units should only be commonly vented with other Category I negative draft appliances per the latest addition of the National Fuel Gas Code. An approved/listed Type "B" venting material is recommended. A negative draft of -0.02" to -0.07" is required in the vent.
