Follow information below to prevent severe personal
injury, death or substantial property damage:
• Donotusegasolinecrankcasedrainingsoranyoil
containing gasoline. See burner manual for proper
fuel oil.
• Donotattempttostartburnerwhenexcessoilhas
accumulated, when unit is full of vapor or when
combustion chamber is very hot.
• Donotstartburnerunlesscollectorhood,breeching
and burner mounting door are secured in place.
• Neverburngarbageorpaperintheboiler.
• Neverleavecombustiblematerialaroundit.
Do not use petroleum-based compounds in boiler
system. Damage to system components can result,
causing property damage.
1. Provide1½”skimpipingfromskimtappingtooordrain.Add
a tee in piping to observe skim water level. Raise waterline to
midpointofskimtapping(seepage26forlocation).
2. Fire burner to maintain water temperature below steaming
temperature during skimming process.
3. Feed in water to maintain water level. Cycle burner to prevent
rise in steam pressure. Continue skimming until discharge is
clear.
4. While boiler is warm, but not hot, drain boiler through drain valve.
5. Remove skim piping. Close drain valve. Fill with fresh water
to normal waterline. Start burner and steam for 15 minutes to
remove dissolved gases. Stop burner.
6. Check traps and air vents for proper operation.
7. Process may need to be repeated after several weeks of
operation.
Fill the system
1. Donotlluntilboilerisreadytobered(exceptforleaktests).
2. Filltonormalwaterline(centerofgaugeglass),asindicated
on jacket front panel.
3. BoilerwaterpH7.0to8.5isrecommended.
FailuretomaintainrecommendedpHlevelcancause
section failure and leaks.
4. Follow“Skimsteamboiler”toensureproperoperation.
Tips for steam systems

waterwillreduceboilerlife.Mineralscanbuildupinsections,
reducing heat transfer and causing cast iron to overheat,
resulting in section failure.
Failure to maintain recommended pH and repair
leaks can cause section iron corrosion, leading to
section failure and leaks. Do not use petroleum-
based sealing or stop-leak compounds in boiler
system. Damage to system components can result.

treatment company.
Skim steam boiler:
Steam boilers must be cleaned to remove any
impurities. Failure to properly clean can result
in violent water level fluctuations, water passing
into steam mains, or high maintenance costs on
strainers, traps or vents. Skim boiler only. Do not
clean old piping or leaks can occur.
Place in operation
1. Verifyboilerislledwithwatertonormalwaterline,asindicated
on jacket front panel.
2. Openburnermountingdoorandverifyreartargetwall,oorand
burner door insulations are in proper position and condition.
3. Verifyburnermountingdoorisclosedtightlyandburnerwiring
harness is connected securely.

CO2valuewillvaryandshouldbeadjustedforcleanandsafe
combustion operation. Seasonal variations as well as sufficient
combustion air supply can affect proper combustion and boiler
performance. The burner should only be adjusted by a service
professional with appropriate instrumentation.
Makenal burner adjustments using combustion
test equipment to assure proper operation. Do not
fire boiler without water. Sections will overheat,
damaging boiler and resulting in substantial property
damage.
5. Checkboilerandsystempipingforleaks.See“Tipsforsteam
systems” on this page.
6. Inspectbreechingandventingforproperoperation.
