NOTICE

This boiler has a  limited warranty,  a copy of w hich is  printed on the  back of this manual.

It is the responsibility of the installing contractor to see that all controls are correctly installed

and are operating properly when  the installation is complete.  The warranty for this boiler is valid

only  if  the  boiler has  been  installed,  maintained  and  operated  in  accordance  with  these

instructions.

WARNING

Boiler materials of construction,  products of combustion and the fuel contain alumina,  silica,

he av y met als, c arbo n mon oxide, nit rogen oxides , a lde hyd es a nd/or othe r tox ic or harm ful

substances which can cause death or serious injury and which are known to the state of California

to  cause cancer, birth defects and other reproductive harm.  A lways use proper safety clothing,

respirators and equipment when servicing or working nearby the boiler.
This boiler contains very hot water under high pressures.  D o not unscrew any pipe fittings nor

attempt to disconnect any components  of this boiler without positively assuring the water is  cool

and has no pressure.   Always  wear  protective  clothing and  equipment  when installing,  starting

up or servicing this boiler to prevent scald injuries.   Do not  rely on the pressure  and temperature

gauges to determine the temperature and pressure of the boiler.  This boiler contains components

which  become very hot when the  boiler is  operating.   Do  not  touch any  components  unless they

are cool.
This boiler must be properly vented and connected to an approved vent system in good condition.

Serious property damage could result if the boiler is connected to an unapproved vent system

.

This  boiler needs fresh  air  for safe  operation and must be installed so there  are  provisions  for

adequate combustion and  ventilation  air.
The interior  of  the venting and air intake  systems must be inspected and  cleaned before the start

of the heating season and should be inspected periodically throughout the heating season for

any obstructions.  C lean and unobstructed venting and  air intake systems are necessary to allow

noxious fumes that could cause injury or loss  of life to vent safely and will contribute toward

maintaining the  boiler's  efficiency.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start

without service - If damage due to frozen pipes is a possibility, the heating system should

not be left unatttended in cold  weather; or appropriate safeguards and alarms should be installed

on the heating system to prevent damage if the boiler is inoperative.
This boiler is designed to burn No. 2 fuel oil only.  D o not use gasoline, crankcase drainings, or

any oil containing gasoline.   Never burn garbage or  paper in this  boiler.   Do not  convert  to any

solid fuel (i. e. wood, coal) or gaseous fuel (i. e. natural gas, LP/propane).  All flammable debris,

rags, paper, wood scraps, etc., should be kept clear of the boiler at all times.  Keep the boiler area

clean and free of fire hazards.
All boilers  equipped w ith Burner Swing Door have a potential hazard which can cause severe

property damage, personal injury or loss of life if ignored. B efore opening sw ing door, turn off

service switch to boiler and disconnect tw o halves of Burner Swing Door Interlock wiring harness

to  prevent accidental firing  of  burner outside  the combustion  chamber.  Be sure to  tighten swing

door fastener completely  and reconnect two halves of Burner Swing Door  Interlock  when  service

is completed.
