PART 3 – MAINTENANCE PROCEDURES
The appliance must be inspected and serviced annually, preferably at the start of the heating season, by a qualified service technician.
In addition, the maintenance and care of the appliance as outlined in this manual must be performed by the user/owner to assure
maximum efficiency and reliability. Follow the maintenance procedures given throughout this manual. Failure to perform the service and
maintenance or follow the directions in this manual could damage the appliance or system components, resulting in substantial property
damage, severe personal injury, or death.
A. DAILY MAINTENANCE – TO BE PERFORMED BY OWNER
Check the Surrounding Area
To prevent the potential of substantial property damage, severe personal injury, or death, eliminate all the materials listed in Table 1
from the area surrounding the appliance and the vicinity of the combustion air intake. If contaminates are found:

Remove products immediately from area.

If contaminates have been there for an extended period, call a qualified service technician to inspect the appliance for possible
damage from acid corrosion.
If products cannot be removed, immediately call a qualified service technician to re-pipe the combustion air intake piping away from the
contaminated areas.
Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other flammable vapors or liquids near the appliance. If found, remove these materials
immediately.
Air Contaminates
If allowed to contaminate combustion air, products containing chlorine or fluorine will produce acidic condensate that will cause
significant damage to the appliance. Read the list of potential contaminates and areas likely to have these contaminates in Table 1. If
any of these contaminates are in the room where the appliance is located, or combustion air is taken from one of the areas listed, the
contaminates must be removed immediately or the intake pipe must be relocated to another area.
Ensure the Appliance Cabinet is Closed
Ensure the appliance cabinet is closed. Tighten the upper screw to secure it. The cabinet must be closed while the appliance is running.
Check the Power Source
Make sure the power cord is properly connected. The main power line is connected to the manual switch box inside the appliance.
Check the Status of the Control Panel
Observe the Control Panel to ensure the appliance is powered on, and to check for any error codes. Clear any debris from the panel.
Check Exhaust Vent and Intake Pipe Terminations
Verify that the appliance exhaust vent and intake pipe terminations are clean and free of obstructions. Remove any debris from the
exhaust vent or intake pipe openings. If removing the debris does not allow the appliance to operate correctly, contact your qualified
service technician to inspect the appliance and the vent system.
