Lighting Instructions - Mendota DXV-42 Installation & Operating Instructions Manual

IMPORTANT: Be sure all items on "INSTALLATION CHECK OFF LIST" (pg. 25) have been completed!
CAUTION: If the pilot goes out, be sure to wait a minimum of five minutes before relighting - be sure to always remove the
glass before relighting the pilot.
1. Remove glass door (see pg. 19) - ALWAYS LIGHT PILOT WITH GLASS REMOVED
2. Make sure any gas supply shut-off cocks are open and Thermo-
stat is "OFF".
3. Push in Gas Cock Dial Slightly and turn clockwise to "OFF".
NOTE: Dial cannot be turned from "PILOT" to "OFF" unless
dial is pushed slightly.
DO NOT FORCE
!
4. Wait five (5) minutes to allow gas, which may have
accumulated in main burner compartment to escape.
If you smell gas STOP.
5. Turn Gas Cock Dial Counterclockwise to "PILOT" position.
6. Depress Gas Cock Dial and push in red Piezo igniter button. Once pilot
ignites, continue depressing dial for about ½ minute. If pilot does not remain ignited, repeat operation allowing a
longer period before releasing Gas Cock Dial.
IMPORTANT: After pilot is lit, system millivolt readings and gas pressure should be taken by qualified installer.
Pilot flame must register a minimum of 460 millivolts (See pg. 31)
7. After pilot is lit and before installing logs, turn Gas Dial to "ON" and "cycle" the burner on/off to make certain it
ignites promptly and that the flame runs smoothly around burner curve and promptly lights entire burner.
8. With pilot operating, install log module and coals (see pg. 20-24). With logs/coals in place, "cycle" the burner
again to make sure of prompt ignition of burner and that the flame runs smoothly around entire burner. NOTE:
Logs will produce a strong, acrid odor on initial contact with flames.
9. Reinstall glass front by "hanging" slots on upper edge of door over tabs on upper edge of firebox opening.
Then "swing in" lower edge of door. Carefully pull out the two (2) Spring Loaded Door Holding Bars located
under the doorframe. Raise Bars and fit Bars firmly into Bar Holding Brackets on door frame (see instructions
pg. 19).
NOTE: Be sure doorframe is "centered" in firebox opening. To "center": Release Door Holding Bars, with
door "hanging" in upper slots "slide" door frame (within the slots) to center of firebox. Replace Door Holding
Bars.
10. Turn Gas Dial counterclockwise to "ON" then set Thermostat or push Remote Control to turn on burner.
11. Main burner should now light IMMEDIATELY and flame should not "lift" off burner. If there is any delay in
ignition or if flame is "lifting off" burner, turn off burner and carefully check for proper installation of logs/coals,
vent system and proper pilot flame impingement on burner and thermopile. Logs or coals must not block pilot
flame or main burner flame. Vent system must be leak proof.
DO NOT PROCEED WITH OPERATION UNLESS BURNER "CYCLES" ON/OFF WITHOUT DELAYS!
12. To reduce heat output, turn Hi/Lo Knob counterclockwise to desired temperature (see FIGURE 5: Gas Valve).
Heat output can be reduced by up to 13,000 BTUH (1/3).
NEVER "over fire" by increasing BTUH above nameplate specifications.
NEVER turn down (reduce) pilot flame below the minimum 460 millivolts.
13. Open windows for first two hours of operation.
NOTICE: Initial heater start-up will cause some NON TOXIC "off gassing" of adhesives, gasket binders, paint and other materials.
Most nuisance odors will be eliminated after the first two hours of operation; however, slight amounts may be present during first 24
.
hours of initial operation
SHUT DOWN PROCEDURE:
1. Turn Remote Control or Thermostat to "OFF". Pilot will remain lit for return to normal service.
2. For complete shutdown turn Gas/Pilot Knob (see FIGURE 5: Gas Valve) to "OFF".
