causes. If dra; is excessive, review instructions on 
installing a barometric damper.

PROPER CHIMNEY CONNECTION

  

e boiler must be connected to a Class A 

chimney. Use of aluminum Type B gas vent for solid 
fuels is unsafe and prohibited by the National Fire 
Protection Association Code.  

ere are three types 

of Class A chimneys:

1. Masonry with a tile liner, including brick, 

block, stone, etc. It must be supported by a ground-
level foundation. 

2. Insulated “Class A” manufactured chimney, 

listed and certi9ed by a national test agency. 

3. Triple-walled metal “Class A” chimney, listed 

and certi9ed by a national test agency.

If your masonry chimney has not been used for 

some time, have it inspected by a quali9ed person 
(building inspector, 9re department personnel, etc.). 
If a listed and certi9ed manufactured chimney is to 
be used, make certain it is installed in accordance 
with the manufacturers instructions and all local 
codes. Use only the manufacturer's parts, and use all
parts required in order to follow the manufacturer's 
guidelines. Do not use makeshi; installation 
techniques. A Multi-Fuel boiler can perform only as 
well as its venting system allows it to.

The chimney selected must comply 
with the requirements for type HT 
chimneys with UL 103 or ULC S629 
ratings. Do not use makeshift 
compromises during construction.

IN CASE OF CHIMNEY FIRE

1. Be sure everyone is out of the house.

2. Call the 9re department. (In the event the 9re

is out before they get there, you will want 
them to inspect the structure and make sure 
there is no latent damage or hazard.)

3. Shut the boiler down by turning the main 

power o<.

4. If you have a chimney 9re, use a chemical 

Eare type 9re extinguisher. If you don’t have 
an extinguisher, go to step 4.

5. Using a water hose, wet down the area of the

roof surrounding the chimney. Do not wet 
the chimney itself or try to put water down 
the Eue as it will very likely damage the Eue 
tiles.

6. Contact a chimney professional to inspect 

your chimney for damages.

IN CASE OF RUNAWAY FIRE

1. Shut the boiler down by disconnecting 

power.

2. Be sure the dra; inducer is o< and/or make 

sure the barometric damper opens. 
(Excessive dra; can cause a runaway 9re.)

3. Maintain continued circulation of boiler 

water to remove heat from the boiler and if 
boiler is equipped with a domestic coil run 
hot water.

Use of aluminum Type B gas vent 
for solid fuels is unsafe and 
prohibited by the National Fire 
Protection Association Code.
