Will a gas heater operate at the low speed of a dual speed motor?
Reply
Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.

What size gas line do I need for the 333,000 but unit?
Reply
Hi. The gas line will be based on the run from the regulator to the unit then downsized to 3/4" at the gas valve. You can use the chart(s) on page 14 of the Max-E-Therm Owner's Manual.
