Sides of the HEATMOR™
Principle of the Sides
The sides of the furnace are clad with your choice of steel siding.
The steel siding provides a dry covering to protect the insulation
of the furnace.
Maintenance / Result
Inspect the sides of the furnace once a year to verify that none
of the screws have broken. A large number of broken screws can allow
damage to the furnace siding. Ensure there is a good seal so no water
can enter into the insulation covering the sides of the water jacket.
Removal and Replacement
If the sides have been damaged or if you would like to change the color
of your unit, they can be replaced with different steel siding. Follow the
following steps or contact your local dealer.
1) Remove all the screws holding the damaged steel siding
secure.
2) Lift the old steel off the furnace.
3) Install the new steel siding.
4) Secure the new steel to the frame of the furnace.
Insulation
Principle of the Insulation
The insulation helps retain the heat in the water, which has been heated by
the fire. It also provides a heat barrier to ensure that the outer steel siding
does not resease any heat.
Maintenance / Result
It is important to keep the insulation dry. Wet insulation loses its R-Value.
Keep the base of the furnace sealed to prevent small rodents from making
nests or wrecking the insulation.
Removal and Replacement
To remove and replace the insulation, refer to the preceding removal and
replacement steps involving the roof and siding. If you have any further
questions, please contact your local dealer.
