Reinstalling Heat Exchanger - Pentair Pool Products MiniMax NT Series Service Manual

Maintenance -
1. Inspect fire box for damage or cracks that would allow
heat to leak out into the outer cabinet and controls.
2. Remove any old sealant from fire box.
3. Apply new sealant to the fire box using a quality
industrial grade R.T.V. or equivalent. The sealant must
completely seal the space between the heat exchanger
and fire box, so that when the heater is firing, heat does
not escape to the outer cabinet.
4. Place heat exchanger into the box and push down firmly,
until the heat exchanger sets solidly on the fire box.
