Unit Maintenance

Service

The furnace DDC controller has diagnostic information

for troubleshooting the furnace operation. Reference

VB1285 and VB1287 documentation below as applicable.

Maintenance

WARNING

Installation and maintenance must be performed only by qualified personnel

who are trained and experienced with this type of equipment and familiar

with local codes and regulations.

WARNING

Improper installation, adjustment, alteration, service, or maintenance can

cause severe personal injury or death. Read and understand this installation

and maintenance manual thoroughly before installing or servicing this

equipment.

WARNING

Electrical shock and moving machinery hazard.

LOCKOUT/TAGOUT all power sources prior to servicing the equipment.

Electrical shock can cause injury, death, and property damage. More than

one disconnect may be required to de-energize unit. All start-up and service

work must performed only by trained, experience technicians familiar with

this type of equipment. Read and follow the MicroTech controller manual

before operating or servicing. Bond the equipment frame to the building’s

electrical ground through the grounding terminal or other approved means.

CAUTION

Hot surface hazard. May cause minor to moderate personal injury. Allow

burner assembly and chimney flues to cool before servicing equipment.

CAUTION

Prevent snow levels from blocking airflow into the furnace vestibule and

combustion air inlet. Ensure snow does not accumulate and interfere with

the operation of electronics within the vestibule.

Planned maintenance is the best way to avoid unnecessary

expense and inconvenience. Inspect the heating system

at regular intervals by a trained and experienced service

technician. The following service intervals are typical for

average situations but should be adjusted per site conditions.
Fuel pressure and control settings should be made only by

trained and qualified personnel.

Always replace covers on burner controls and boxes as the

electrical contacts. Perform maintenance of controls, gas

valves, and other components in accordance with the furnace

module instruction manual.

Monthly

Check cabinet air filters and replace if dirty. After heavy

snowfall verify that combustion air intakes are not blocked by

snow. Periodically check during periods of snow accumulation

as drifting may also lead to combustion air intake blockage.

Twice Yearly

Combustion Air:

Check combustion inducer fan for dirt

buildup and lint. Check combustion air intake louvers and

flue box/vent for accumulation of dirt and debris.

Cleaning:

Inspect and clean flue tubes and combustion

chamber. Keep burner vestibule clean. Dirt and debris

can result in poor combustion and lower efficiency.

Yearly

Debris:

Check vent terminal screens for blockages and

accumulation.

Heater and the Venting System:

Shall be inspected

once a year by a qualified service agency.

Gas Train:

Check all valves, piping and connections for

leakage with a rich soap solution or UL 913 combustible

gas leak detector. Any bubbling is considered a leak and

must be eliminated. Inspect and clean flame rod, ignition

electrode, and burner manifold.

Condensate Pan and Drain:

Remove any debris that

may have accumulated in the drain pain and drain.
