PREVENTATIVE MAINTENANCE
Preventative Maintenance can provide measurable improvements in system performance as well as a marked
reduction in comfort complaints. The customer should always remain aware of preventative maintenance
actions that could help them avoid unnecessary shutdown time and save them repair expense.
Preventative Maintenance Checklist:
1
Ground Fault Interrupter Receptacle
> Should be tested monthly to insure proper and safe operation.
(a) check with a circuit tester to determine if the polarity is correct. (b) Press the test button, the reset
button should pop out indicating the interrupter has tripped. Press the reset button to restore to normal
operation.
2
Heater Piping
> Check all piping occasionally on back of heater for any possible water leaks. Water leaks
on heater components can cause electrical shorts, damage to component parts and insulation.
3
Low Water Light
>Check the low water warning light each week for proper operation to avoid low water
or over filling in heaters with electric make-up water systems, See service information section in owners
manual for proper checking procedures.
4
Ash Bin
> Keep ash bin from ash buildup. Remove ashes before they build up to the level of the grates.
This will restrict proper air flow and cause the grates to warp. Leave at least 1/2” to 1” of ashes in bottom
of ash pan to protect the bottom from burnout.
5
Damper/Draft System and Smoke stack
> Check at least every two weeks for build up of ash, tar, or
any other material that could restrict the amount of air flow required. Oil the blower motor bearings prior
to each heating season with 10 to 20 drops of electric motor oil.
6
Door Seals
> Check firebox door and ash door seals occasionally for damage or obstructions that would
affect an airtight seal.
7
Preseason Maintenance
> Review preseason heater maintenance section in owners manual prior to each
heating season.
