Maintenance; Maintenance Descriptions - Ace Heating Solutions Atlas A050 Operating And Maintenance Manual

7 Maintenance

Maintenance is an important part of keeping the Atlas boiler running efficiently and for a long period of time. Ace
recommends that a maintenance schedule be kept. For extended warranty, schedule must be kept and made available to
Ace if failure occurs. A document must be produced for every year of operation, so it is recommended that copies of the
maintenance schedule be made before it is used. The Ace approved maintenance schedule with descriptions is listed
below:

7-1 Maintenance Descriptions

Test operating temperature controls (should be done monthly):
Test operating controls by adjusting the temperature necessary to check burner operation.
Pilot and Main Flame Signal (should be done monthly):
Using a voltmeter, plug into the flame detection port on the flame safeguard. The voltage reading should be between 1-15
VDC. Additionally, remove the UV scanner and using soft cloth wipe the lens clean.
Air Filter (should be done monthly):
The air filter should be inspected and cleaned monthly, and should be replaced once it is restricting air flow. As the air
filter restricts the air flow, it will limit the input possible for the boiler. A dirty filter is equivalent to adding on venting to the
air intake. A single replacement filter is provided with the unit on shipment. To check air filter, remove two screws on the
top of the air filter box and open door.
Check Condensate Drain System (should be done monthly):
Replace condensate treatment kit (if purchased) when filter expires.
Observe condition of main flame (should be done monthly):
Check to make sure high fire flame is blue. If the flame is yellow, adjust gas valve until blue flame is achieved following
initial set up procedure. Normal low fire flame is a yellowish-orange.
Leak test for gas valve, pilot assembly and blower (Semiannually)
With the unit running, use soapy water to spray around the pilot assembly, blower, and gas train. If bubbles form, then a
leak is present.
Cleaning the Burner/Coils (should be completed annually):
1) Shut off the manual gas cock at gas inlet.
2) Remove electrical power to boiler
3) Remove top and front panel
4) Remove nuts connecting blower to the top plate
5) Remove combustion assembly
6) Remove burner
7) Use low pressure air to remove dust and a clean soft cloth to wipe the inside of the burner (do not wipe the
mesh/outside of burner)
8) While burner is removed, check coils with flashlight for soot and remove with brush or vacuum
9) Spray coils with high pressure water to remove any foreign materials
10) Check for corrosion of burner, replace if necessary
11) Reassemble burner and combustion assembly as seen in figure 7
Examine Vent System (Annually)
At all connections check for air leak while unit is on low fire so as not to burn yourself.
Examine Joint and Pipe Connections for Tightness (Annually)
Check all water pipe connections for leaks while unit is on low fire. If a leak is present around a fitting attempt to tighten
the fitting. If a leak is present by a braze or in the middle of the pipe, contact factory.
Check Pipe for Corrosion/Deterioration (Annually)
Check all gas, water, and air pipes to for corrosion and deterioration. If any corrosion or deterioration is present, please
contact factory.
Combustion Tests (should be completed semiannually):
