Care and Cleaning
To keep your Del Rey Heater in maximum performance, we recommend the follow
ing to be perform annually.
1). With an air hose regulated to 30 psig, blow off any dust and dirt that has accu
mulated around the burner and inside the control compartment of the heater.
Proper eye protection required.
2). From the front of the heater, direct the air hose from a distance of approximately
12 inches over the entire exposed area of each burner's ceramics.
3) Do not insert air hose into the inlet of the burner.
4) Remove main burner orifice, clean and re-install.
5) Check to insure heater is securely mounted and the clearance from combustible
materials is maintained.
6) If additional service to the heater is required contact your local dealer or the
factory.
Before Calling Service
If no glow from hot surface igniter; or if gas valve doesn’t work:
a) Check power supply, should have 24 volts between power wires. Use volt meter
between inlet wire and ground terminal inside heater control box to measure
24 volts.
b) Check continuity by using an ohmmeter. Check resistance between valve wire
and ground. Ohmmeter should read almost no resistance or (
# ohms) through
valve. If high resistance, check wire connectors.
c) Be sure connectors are fully inserted into ignition control.
If insufficient gas flow:
a) Manual gas valve not fully to “ON” position. Turn valve handle to full “ON”
position. Also ensure internal lever is in the “ON” position (as shown on page 10).
b) Burner orifice plugged. Remove service panel, remove burner orifice (7/16
”
wrench) and thoroughly clean. Spiders often crawl into orifice hole and make a
web blocking the orifice.
