CAUTION: Use of eye

protection is

recommended.

Each section of this heater is equipped with a TCORE2® heat exchanger (U.S. Patent No. 6,889,686). Size 400 has one; Size 800 has two; and Size 1200 has three.

Remove any external dirt or dust accumulation. Visually check each heat exchanger for cracks and holes. If a crack or hole is observed, replace the heat exchanger.

NOTE: Inspection of the lower portion of the heat exchanger is done with the burner removed. See the Burner Service section below for information on inspecting the lower portion of the heat exchanger.

Each section of this heater is equipped with a TCORE2® burner (U.S. Patent No. 6,889,686). Size 400 has one; Size 800 has two; and Size 1200 has three.

Inspect each burner/control compartment annually to determine if cleaning is neces- sary. If there is an accumulation of dirt, dust, and/or lint, clean the compartment and follow the instructions below to remove and clean the burner.

1.Outside the cabinet, shut the gas supply off at the manual valve ahead of the union.

2.Turn off electric supply.

3.Disconnect the gas supply at the union outside of the cabinet.

4.Remove the access panel.

5.Disconnect the Gas Train and Move It Out of the Way - At the gas valve, mark and disconnect the wires. Disconnect the union on one or both sides of the gas line inside of the heater. Carefully remove the burner orifice and orifice adapter locking nut. Slide the orifice adapter out through the bracket on the burner.
