Operating instructions

Relief Valve
Thisvalveshould open automaticallyif the systempressure exceeds
the pressure rating (usually 30psi) of the reliefvaNe. Should it ever
fail to open under this condition, shut down your system. Drain
the systemuntil systempressure is reduced belowthe reliefvaNe
pressure rating. IfvaNe discharge occurs,or if vaNefails to open
as described above,contact an authorized contractor or qualified
service technician to replacethe reliefvaNeand inspect the heating
systemto determine the cause,as this may indicate an equipment
malfunction.
Thisvalveshould be tested everymonth during periods of boiler
operation, and at the beginning and endof any extended non-service
period. Prior to testing, make certain discharge pipe is properly
connected to vane outlet and arranged soas to contain and safely
dispose of boiler discharge.Test at normal systemoperating pres-
sure. Hold the trip leverfullyopen for at least five secondsin order
to flush freeany sediment that may lodgeon the vane seat. Then
permit the valveto snap shut.
Expansion Tank
Aspreviously noted, this tank may becomewaterlogged,or may re-
ceivean excessof air.Frequent automatic opening of the reliefvalve
indicateswater logging.A high boiler temperature accompaniedby
unusuallylow radiation unit temperature (and "knocking") indicates
excessairin tank. Tocorrect either condition, closethe valvebe-
tween the boiler and the tank. Drain the tank until it is empty.Check
allthe tank plugs and fittings.Tighten as necessary.Open the vane
between the boiler and tank. Waterwill rise to the normal height in
the tank if you have an automaticfill vane (otherwise, manually refill
the system).
Boiler Flue Passages
Under normal operating conditions, with the burners properly
adjusted,it should not be necessary to clean the boiler flue gas pas-
sages.However,to assuretrouble-free operation, werecommend that
you havethe fluepassages,burner adjustment, and operation of the
controls checkedonce eachyear by a competent ServiceTechnician.
Before The Start Of Each Season
(or whenever systemhas been shut down for some time) recheck the
whole systemfor leaks.., and recheck the boiler andvent pipe for
leaks.Replaceor patch anyboiler sealsthat are faulty.
Vent Pipe
The venting of this unit is very important and the piping should be
checked at least once a month. If the vent piping shows any sign of
leaking, replace it immediately.
Water System
If system is to remain out of service during freezing weather, always
drain it completely (water left in to freeze will crack the pipes and/or
boiler).
Cleaning Your Boiler And Burners
Flue passages between sections should be examined yearly and
cleaned if necessary.
To clean, remove burners, pilot and vent pipe. Remove top and front
jacket panels. Split the silicone seal on the flue collector and the
clean out plates with a razor knife. Remove flue collector. Remove
clean out plates by tapping upwards on the bottom of the plate with a
hammer. Remove loose silicone sealant from sections, flue collector,
and clean out plates.
Clean passageways between sections with a flexible handle wire
brush and a straightened out wire coat hanger. Remove dirt from the
bottom of the boiler and from between sections by vacuuming.
Make sure all flame ports in burners are open and clear. Shake out
or blow out all loose dirt in burners. Reassemble all parts. Seal flue
collector and clean out plates to sections with silicone sealant (400° F
RTV silicone sealant or equivalent). Reseal seams between adjacent
sections where necessary. All joints must be airtight. Be sure to check
tightness of pilot connections and condition of burner flames after
reassembly (see Figures 1S, and 17). Be sure vent pipe connec-
tions to chimney are secure and no obstructions are present.
Blower
Theblowermotor features apermanently lubricated ball bearing
construction. Lubricationisnot required.
Circulator Pump Isolation Valves
The isolation vanes in the circulator pump flanges should be oper-
ated manually once or twice per year to prevent the vanes from be-
coming stuck in the open position. Rotate the vanes from the open
position to the closed position and back to the open position.
