of water for satisfactory operation. The red, or fixed, hand on the combination altitude gage and
thermometer is normally set to indicate the amount of pressure required to fill the system with cold
water. Water should be added to the system until the black hand registers the same or more than the red
hand. To insure that the system is full, water should come out of all air vents when opened.
The water must enter the system as slowly as possible, and in proportion to the rate of air purge from the
components involved. In the case of a system with a closed expansion tank, water is injected until the
pressure gauge reaches the static pressure for the tank. Then proceed to heat the water to the maximum
allowed plant temperature. During this operation, the air in the system purges from the automatic or
manual air separators fitted to the system. On completion of the air purge, bring the pressure to the set
value and close the manual and/or automatic water supply valve.
6.6 Firing a new boiler
Commissioning and firing a new boiler is to be conducted by your installer. This process is beyond the
scope of this manual.
This is to be conducted by qualified personnel only. Refer to the burner manual
for more information about starting up the burner.
When tuning the flame in your new boiler, the flame should not be allowed to impinge upon the back of
the furnace.
A boiler tuned with flame continuously impinging upon the back of the furnace will void
the warranty.
Also see the boil out instructions and start up procedures for details on firing the boiler for
the first time.
6.7 Boil-out procedure
All new boilers must be boiled out or Triad Boiler Systems will void the warranty!
Before introducing the boil-out chemicals to any drain system, check local environmental regulations to
ensure you are in compliance.
It is necessary to clean the inside of the new boiler of oil and grease. Failure to remove these materials
will result in your unit foaming, priming, and pulling over. These contaminants must be removed to
provide clean heat transfer surfaces. Before boil-out procedures may begin, the burner must be ready for
firing and the operator must be familiar with the procedure outlined under burner operation. SBT-710 is
the chemical recommended for the cleaning of boilers. Dosage is one (1) gallon per fifty (50) gallons of
water in the boiler. The operator must become familiar with the information in the SBT-710 technical data
sheet and the MSDS.
1.
Close off supply and return water valves and remove safety relief valves.
2.
An overflow pipe should be attached to either the vent connection or a safety valve connection
located at the top center of the boiler and routed to a safe point of discharge, in compliance with
