DO NOT install a relief valve with a pressure higher
than 30 PSIG
. is is the maximum allowable relief
valve setting for the Ultra boiler.

1. See Figure2 for reference in following steps.
2. Remove supply line tees* and 3/4” elbow from accessory bag.
Pipe to boiler supply connection as shown. Use pipe dope spar-
ingly. (* 1”x1”x1/4” and *1”x1”x3/4” tees with Ultra-80 to -230
or * 1-1/4”x1-1/4”x1/4” and *1-1/4”x1-1/4”x3/4” tees with Ultra
299/399.
3. Temporarily plug the ¾” relief valve tapping in the street elbow
with a ¾” NPT pipe plug.
4. Connect a hose to the boiler drain valve, the other end connected
to a fresh water supply. Make sure the hose can also be used to
drain the boiler aer test.
5. Connect a nipple and shuto valve to system supply connection
on the supply tee. is valve will be used to bleed air during the
ll. (Valve and nipple are not included with boiler.)
6. Connect a shuto valve to system return connection. (Valve is not
included with boiler.)
7. To avoid getting water on boiler, you may want to pipe street elbows
on top of shuto valves and attach catch-buckets beneath.
8. If convenient, install the boiler circulator and any other piping
compatible with Figure2 that would still allow bleeding air from
shuto valves.
9. Follow guidelines in this manual for piping components, locations
and sizing.

1. Open the shuto valves you installed on supply and return con-
nections.
2. Slowly open boiler drain valve and fresh water supply to ll boiler
with water. e boiler will ll quickly because of its low water
content.
3. When water reaches shuto valves, close boiler drain valve.
4. Close shuto valves.
5. Slowly reopen boiler drain valve until test pressure on the pres-
sure/temperature gauge reaches at least 45 psig, but no higher
than 55 psig.
6. Hold at test pressure for 10 minutes.
Do not leave boiler unattended. A cold water ll could
expand and cause excessive pressure, resulting in severe
personal injury, death or substantial property damage.
7. Make sure constant gauge pressure has been maintained through-
out test. Check for leaks. Repair if found.
Leaks must be repaired at once. Failure to do so
can damage boiler, resulting in substantial property
damage.
Do not use petroleum-based cleaning or seal-
ing compounds in boiler system. Gaskets and
seals in the system may be damaged. is can
result in substantial property damage.

1. Disconnect ll water hose from water source.
2. Drain boiler through drain valve. Remove hose aer
draining.
3. Remove nipples and valves unless they will remain for
use in the system piping.
4. Remove plug from relief valve street elbow. See page9
to install relief valve.
