Maintenance; Cleaning The Standing Pilot Control System; Cleaning Automatic Direct Electronic Ignition System - Majestic fireplaces NVSTR36 Installation And Operating Manual

Keep the control compartment, logs and burner area
surrounding the logs clean by vacuuming or brushing at
least twice a year. THE LOGS CAN GET VERY HOT
— HANDLE ONLY WHEN COOL.
Always turn off gas to the pilot before cleaning. For
relighting, refer to lighting instructions located on the
front cover plate.
Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obstacles
and materials.
Leave at least 36" clearance from front of appliance to
combustibles.
Cleaning the Standing
Pilot Control System
The burner and control system consists of:
•
main burner
•
gas orifice
•
pilot burner
•
thermopile
•
combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require ad-
justment. If repair is necessary, it should be performed
by a qualified technician.
In order to properly clean the burner and pilot assem-
bly, turn off the gas to the unit, open the glass door
(if used), remove logs exposing the burner and pilot
assembly. Clean all foreign materials from the top of the
burner. Check to make sure that burner parts are clean.
Visually inspect pilot. Brush or blow away any dust or
lint accumulation If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8" or 1/2" of the thermopile should
be engulfed in the pilot flame. (Page 12, Fig. 16)
To adjust pilot burner, adjust pilot screw marked "pilot"
for proper size:
1. Remove pilot adjustment cap.
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
The air shutter is set at factory; no adjustment should
be necessary.

Maintenance

The Electronic Ignition burner/ control system consists
of:
•
•
•
•
Taking care of the Electronic Ignition units is almost
identical to taking care of the Standing Pilot models.
(See the Maintenance section on page 16.)
The hot surface ignitor is the only component which
requires EXTREMELY DELICATE HANDLING. The
ignitor is made of silicone carbide which is a very brittle
material.
