Sequence of Operation 1 2 Combustion gases generated by the Premix Power Burner travel through three heat exchangers. The combustion gases enter the 1st pass heat exchanger at a temperature above 2000°F and then travel down the 8" heat exchanger tube. 3 When the combustion gases reach the 1st pass collector at a temperature near 1100°F, the gases are then redirected upwards into two 4" 2nd pass heat exchanger tubes. 4 The gases then move into the 2nd pass collector, where the temperature has now been reduced down to approximately 500°F. The combustion gases are then forced downward through eight 2" 3rd pass heat exchanger tubes and reach the exhaust collector at a temperature of approximately 120°F. Venting Options • * Flexible Venting up to 240 ft. • * • Optional Concentric Vent Termination Kit – available in 2" or 3" Ability to vent with 2", 3", 4" or 6" PVC, CPVC, ABS or PP Pipe (Canada must use specific ULC S636 vent material) *Review, spec sheet and manual for venting limitations.
