1. 

Check your local codes and utility requirements 

before installation. Installation must be in accordance 

with their directives, or follow 

NFPA 31 Standard for 

Installation of Oil Burning Equipment

, latest revision.

2. 

Before servicing, allow boiler to cool. Always shut off 

any electricity and oil to boiler when working on it. 

3. 

Inspect oil line and connections for leaks.

4. 

Be certain oil burner nozzle is the size required. Over-

firing will result in early failure of the boiler sections. 

This will cause dangerous operation.

5. 

Never vent this boiler into enclosed space. Always vent 

to outside. Never vent to another room or inside a 

building.

6. 

Be sure there is adequate air supply for complete 

combustion.

7. 

Follow regular service and maintenance schedule for 

efficient and safe operation.

8. 

Keep boiler area clean and free of combustible material, 

gasoline and other flammable vapors and liquids.

9. 

Oil burners are not do-it-yourself items. This boiler 

must be installed and serviced by qualified professionals 

using combustion test instruments.

 WARNING

Burn and scald hazard.  Safety relief valve could       

discharge steam or hot water during operation.       

Install discharge piping per these instructions.

!

     

10. 

Be aware when piping the safety relief valve if system 

pressure exceeds safe limit of 30 pounds per square 

inch, the safety relief valve will automatically lift 

open. Lifting of the safety relief valve can discharge 

large quantities of steam and hot water, which may 

damage the surroundings. Before installing the safety 

relief valve read the manufacturer’s instructions and 

maintenance section of the manual on safety relief 

valves.

11. 

Installation and sizing of the expansion tank must 

consider heating systems total water volume, 

temperature, boiler initial fill pressure, and system 

arrangement. Improperly installed and sized expansion 

tank may result in frequent lifting of the safety 

relief valve or other heating system problems. For 

proper installation, sizing, and maintenance of the 

expansion tank follow guidelines established by tank 

manufacturer.

12. 

Expansion tank performance and life expectancy can 

be hindered by overfilling the boiler. Recommend initial 

fill pressure of 10-12 psig. For higher fill pressures 

expansion tank’s air charge will need to be increased to 

match fill pressure. Consult manufacturer’s guidelines 

for sizing and selection.

13. 

Purging the heating system of air and gases when 

first putting boiler into service is critical for proper 

circulation and quiet performance. Once air and gases 

are purged, for boiler installations using float type 

vents, air vents should be closed for normal operation. 

If air is heard or noticed by loss of heat, purge system 

and open vents for short period of time.

SAFE INSTALLATION AND OPERATION

NOTICE

This boiler has been designed for residential 

installations. If used for commercial applications, 

all jurisdictional requirements must be met. This 

may require wiring and/or piping modifications. 

Manufacturer is not responsible for any changes to 

the original design.

 WARNING

Fire, explosion, burn, scald hazard.  Use only 

number 2 fuel oil. Do not use gasoline, kerosene, 

crankcase oil or any oil containing gasoline. Failure 

to follow these instructions could result in death or 

serious injury.

!

     

 WARNING

Combustion chamber insulation in this product 

contains ceramic fiber material. Ceramic fibers can 

be converted to cristobalite in very high temperature 

applications. The International Agency for Research 

on Cancer (IARC) has concluded, Crystalline silica 

inhaled in the form of quartz or cristobalite from 

occupational sources is carcinogenic to humans 

(Group1). Avoid breathing dust and contact 

with skin and eyes. Use NIOSH certified dust 

respirator (N95). This type of respirator is based 

on the OSHA requirements for cristobalite at the 

time this document was written. Other types of 

respirators may be needed depending on the job 

site conditions. Current NIOSH recommendations 

can be found on the NIOSH website 

 https://

www.cdc.gov/niosh/topics/silica/.

  approved 

respirators, manufacturers, and phone numbers are 

also listed on this website. Wear long-sleeved, loose 

fitting clothing, gloves, and eye protection. Apply 

enough water to the combustion chamber lining to 

prevent dust. Wash potentially contaminated clothes 

separately from other clothing. Rinse clothes washer 

thoroughly.

NIOSH stated First Aid. Eye: Irrigate immediately. 

Breathing: Fresh air.
