Safety Precautions 

          
Do not operate this equipment for anything other than its intended purpose or for anything other 
than in accordance with the instructions contained in this manual and all other instructions 
accompanying the boiler. It is important to observe safety precautions to protect yourself and others 
from possible injury. Observe all safety labels on the boiler. 

 
All electrical and plumbing should be done by qualified personnel and conform to national, 
state and local electrical, plumbing, fire and building codes.  
 

1.  DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE. Never use chemicals or any 
type of petroleum based product, charcoal starter, lighter fluid, lantern fuel, kerosene or any other 
flammable accelerant to start the fire in the firebox of the boiler. Keep all such liquids well away 
from firebox. 
 
2.  If using antifreeze, use only non-toxic, follow manufacturer’s recommendations on mixing ratio 
and test annually per manufacturer’s specs. Keep containers of antifreeze, which is flammable, well 
away from the boiler. 

 

3.  The use of treated wood (painted, treated, etc.) and any other salvaged material that can emit 
toxic gases into the environment and is corrosive towards the components of the appliance is not 
allowed and voids the warranty. 
 
4.  DANGER! Risk of fire or explosion – DO NOT BURN GARBAGE, GASOLINE, NAPHTHA, 
ENGINE OIL OR OTHER INAPPREPRIATE MATERIALS. Flammable liquids household or yard 
waste can reduce the life of the boiler, will void the warranty and is illegal in most areas. 

 

5.  Pause for 30 seconds between the first latch and the safety latch to allow any combustion gases 
to burn off. Always keep fueling and de-ashing doors closed and maintain all seals in good 
condition. 

 

6.  In the event of a runaway fire, make sure all doors are tightly shut, unplug the control power, 
keep the pump running, make sure the blower damper is closed and keep the water jacket full. 

 

7.  WARNING! Risk of fire – Do not operate with fuel loading door open. Do not store fuel or other 
combustible material within the marked installation clearances. Leaving a small crack or opening 
can cause over-heating in the firebox, boiling the water off, damage of the unit and voiding the 
warranty. Inspect and clean the firebox, ash pan and chimney regularly. 

 

8.  CAUTION! Hot surfaces. Keep children away. Do not touch during operation. Always use proper 
care when installing, operating and maintaining the boiler.  

 

9.  Always wear protective gloves and glasses and be aware that hanging and loose clothing can 
catch fire. 

 

10. All doors and covers must be maintained in place at all times, except during maintenance and 
servicing. 

 

11. Do not modify the boiler or controls. Do not connect this unit to a chimney flue serving another 
appliance. 

 

12. Failure to heed these warning or any additional warnings on the boiler may result in an accident 
causing personal injury and damage and void the warranty. 
 

All installation and operation must follow federal, provincial, state and local codes
