REPLACEMENT PARTS and SERVICE
Over Firing of Burner
Never "over fire" units by adjusting gas pressure or drilling out the orifice to increase Btu/hr above
nameplate specifications. Over firing can cause permanent damage to firebox and deterioration of parts and
void warranty.
Maintaining Correct Pilot-Flame, Pilot Outage, and Relighting
The pilot flame
must be checked
during initial installation and annually by a qualified Mendota Technician.
This fireplace uses flame rectification technology. If the pilot flame is turned down too low, the flame sensor
may not detect the pilot flame and the pilot may not stay lit. Do not turn down the pilot flame. The flame
sensor rod may be coated with debris after a few months of use. It is important to clean the flame sensor rod
using emery cloth if flame rectification problems are encountered after use for a few months. Environmental
factors beyond the control of Mendota can cause flame rectification concerns.
How to Access Components
The descriptions below show where the main fireplaces components are located and how to access them for
service. The descriptions show how to access the components after the fireplace has been installed. All
components are also accessible from the outside of the unit before the fireplace is installed.
Pilot
: The pilot is in the center of the firebox between the burners.
Gas Valve
: The main gas valve is located on the left side of the firebox. An inspection panel is provided on the
left firebox wall that allows inspection of the gas valve, wiring, and gas inlet connections.
Complete Valve Assembly
:
To make working on components easier, this fireplace has been designed with
the valve, pilot, shutter boxes, shutter cables and gas lines as part of one assemble that can be removed from
the fireplace. To remove the assembly first remove the inspection panel. This will allow the main gas inlet
and wires to the valve, rear burner solenoid and pilot to be disconnected. After disconnecting the gas line
and wires remove the screws from the valve mounting plate (13 on the left side and two on the floor of the
firebox). Then remove the entire assembly from the firebox.
Ignition Control Module
: The ignition control module is mounted on the left on the floor under a heat shield.
Access to the ignition control module is available through the inspection panel. First remove the inspection
panel. Then locate the two screws holding the heat shield in place above the ignition control module. The
ignition control module is affixed with Velcro to the floor.
