C. Weekly
1. Check combustion safety controls for flame
failure (or other alarm messages).
2. Check all limit controls and low water cutoff as
described above.
3. Check condensate drains for any obstructions.
4. Check carbon monoxide level in flue products.
D. Monthly
1. Check high and low gas pressure interlocks.
Refer to manufacturer's instructions for correct
procedure.
2. Check proper operation of safety relief valve.
3. Check water quality and correct if needed.
4. Inspect boiler air filter.
E. Annually
1. The flue gas passages and the exterior surfaces
of the boiler tubes should be inspected at least
once annually. Any accumulation of soot or
debris should be thoroughly cleaned out.
2. If inspection of the boiler tube surfaces reveals
a build-up of soot (carbon), the tube surfaces
should be thoroughly brushed. Failure to do
so may result in reduced efficiency, fire and
asphyxiation hazards.
3. The boiler pressure vessel and piping should
be checked annually.
4. Inspect the ignition rod for carbon build up.
5. Inspect lens of the ultra-violet (UV) scanner and
remove any debris with soft cloth and make
sure that hole is clear from scanner to burner.
6. Replace air filter.
F. Ignition Assembly Cleaning
1. Disconnect power and shut off the external
manual gas valve to the boiler prior to removing
the ignition assembly.
2. When removing the igniter, extra caution must
be taken to prevent damaging the ceramic
insulator.
3. Remove any excess oxide deposits from the
surface of the igniter with steel wool Do not use
sandpaper, emery cloth or scotch brite pads.

4. Inspect the ceramic insulator for cracks, and if
necessary, replace the igniter.
5. For the Arctic 1000-3000 see Figure 15.
a. Ensure that igniter electrode spacing is within
1/8 inch.
b. After each inspection of the igniter, replace
gasket and apply anti-seize compound to
mounting screws prior to reinstalling them.

6. For ARCTIC 3500-6000 see Figure 16. After
inspection of the igniter, apply anti-seize
compound to igniter threads and replace the
igniter, making sure the flat part along the edge
of the disc is pointed down towards the base
of the boiler.
