GAS-FIRED WATER BOILER SERIES 2 — User’s Information Manual
1. Remove boiler front access door and perform gas leak inspection per steps 1 through 7,
Operating Instructions, page 9. If gas odor or leak is detected, immediately shut down
boiler following procedures on page 9. Call a qualified service technician.
2. Visually inspect for leaks around internal water piping. Also inspect external water piping,
circulators, relief valve and fittings. Immediately call a qualified service technician to
repair any leaks.
Have leaks fixed at once by a qualifed service technician. Failure to comply
could result in severe personal injury, death or substantial property damage.
3. Replace door securely after inspections (see WARNING, page 6).

Maintenance procedures
(continued)
1. Follow “TO TURN OFF GAS TO
APPLIANCE
” on the page 9 of this
manual.
2. Do not drain system unless exposure to
freezing temperatures will occur.
3. Do not drain the system if it is filled with
an antifreeze solution.
4. DO NOT shut down boilers used for
domestic water heating. They must operate
year-round.
1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of
discharge, avoiding any possibility of scalding from hot water.
To avoid water damage or scalding due to valve operation, a metal discharge
line must be connected to relief valve outlet and run to a safe place of disposal.
This discharge line must be installed by a qualifed heating installer or service
technician in accordance with the instructions in the Ultra Boiler Manual. The
discharge line must be terminated so as to eliminate possibility of severe burns
or property damage should the valve discharge.
2. Read the boiler pressure/temperature gauge to make sure the system is pressurized. Lift
the relief valve top lever slightly, allowing water to relieve through the valve and discharge
piping.
3. If water flows freely, release the lever and allow the valve to seat. Watch the end of the
relief valve discharge pipe to ensure that the valve does not weep after the line has had
time to drain. If the valve weeps, lift the seat again to attempt to clean the valve seat. If the
valve continues to weep afterwards, contact your qualified service technician to inspect
the valve and system.
4. If water does not flow from the valve when you lift the lever completely, the valve or
discharge line may be blocked. Immediately shut down the boiler, following the operating
instructions on page 9. Call your qualified service technician to inspect the boiler and
system.
