Cleaning The Standing Pilot Control System; Cleaning The Electronic Ignition System - Majestic 360DVS2 Installation Instructions & Homeowner's Manual

Honeywell Gas Control Valve (Fig. 49)
The Honeywell valve fitted to this unit is suitable for
use with LP or Natural Gas. It is converted to the
required gas application by installing a color-coded
conversion screw.
a) Using a suitable small screwdriver, lift out the
central regulator cap from the "HI/LO" knob on
the valve.
b) Unscrew the exposed conversion screw.
c) Insert the new color coded conversion screw.
Do not overtighten the screw; it must be finger-
tight.
d) Refit the regulator cap.
e) Mount conversion label supplied with the
conversion screw to the valve in a visible
position.

10. Reassemble fireplace in the reverse order, except
for the window frame assembly. Leave this off until
after unit has been checked for leaks and the gas
supply has been bled.
11. After bleeding the gas line and checking for leaks
with a soap solution, replace the window frame
assembly.
12. Fire up the unit. Check for flame impingement on
the logs, adjusting them as necessary.
13. Check manifold and supply pressures against the
appliance specifications.
The procedure for converting from one
gas to another is the same regardless of
the initial gas used. The only variations
are in orifice sizes and component part
numbers. Your authorized service
provider will ensure correct parts are
used.

Cleaning the
Standing Pilot Control System
The burner and control system consists of:
• burner tube
• pilot assembly
• millivolt gas valve
Most of these components may require only an
occasional checkup and cleaning and some may
require adjustment. If repair is necessary, it should
be performed by a qualified technician.
1. Turn off pilot light at gas valve side.
2. Let fireplace cool if it has been running.
3. Remove window frame assembly. (Refer to Window
Frame Assembly Removal section)
4. Remove logs.
5. Vacuum burner compartment especially around
orifice primary air openings.
6. Visually inspect pilot. Brush or blow away any dust
or lint accumulation.
7. Reinstall logs.
8. Ignite pilot; refer to Lighting Instructions.
9. Reinstall window frame assembly.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.

should be engulfed in the pilot flame (Fig. 46, page 26).
To adjust pilot burner (to be done by a qualified
service technician):
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
The primary air shutter is set at factory and should be
adjusted, if necessary, only by a qualified service
technician.
Cleaning Electronic Ignition System
The Electronic Ignition burner/control system consists of:
• main burner
• gas orifice
• pilot burner
• 24VAC valve with transformer
The process for taking care of Electronic Ignition units
is identical to that for taking care of Standing Pilot
models.
• gas orifice
• thermopile
