Flushing
Clogged fluid passages reduce heating efficiency, flow
rate, and pressure. Flush or clean whenever a change in
heating efficiency, flow rate, or pressure is noticed.
1. Follow Pressure Relief Procedure, page 11.
2. Ensure main power is off and heater is cool before
flushing. Use a compatible solvent, and follow flush-
ing instructions in your fluid supply and spray gun
manual. Do not turn on heater until fluid lines are
clear of solvent.
