4.0 MAINTENANCE
The Seton Boiler is a relatively low maintenance appliance but there are a few important operations to per-
form on a regular basis.
1. Check relief valves for leaks. Daily
2. Clean ashes. As needed
3. Test antifreeze. Monthly
4. Lubricate the door hinges. Bi annually
5. Inspection and cleaning of chimney. Annually
6. Inspect insulation and refractory. Annually
7. Test relief valves Annually
4.1 Flushing Procedure
After the first week of operation you can drain and flush the boiler to remove sediment. Refill it with clean
potable water. Boiler water should turn slightly brackish after a few months. This is water that the oxygen
has been eliminated from and never needs to be changed. Any sign of red or rust colored water in the boiler
is a sign of corrosion from oxygen and is a sign that fresh water is coming into the system from fresh
makeup water. This problem is caused from leaks in the system or the boiler blowing water out the relief
valves from improper aquastat settings or under sizing of the dump zone. THESE PROBLEMS CAN VOID
YOUR WARRANTEE.
4.2 Relief Valve Testing Procedure
Once a year pull the lever up on the relief valves and flush the sediment off the seat. Allow the valve to
snap shut and observe if the valve is leaking. Any time the relieve valve is leaking it will need to be re-
placed immediately. Both relief valves can be found at most hardware stores. Check the new ones for the
exact same temperature and pressure settings.
4.3 Antifreeze Solution
Antifreeze should be used for protection and then never more than 35% solution. If you are going to use an-
tifreeze run the boiler for a few weeks first with out any to make sure you have the proper adjustments on
the dump zone and aquastats. Otherwise you could dump antifreeze out of the system. You can place a
bucket under the relief valves to collect spilled antifreeze.
