Mounting

The Sig heaters have the appropriate brackets to secure the heater to the

bulkhead. The drip tray will then fit under the bottom of the heater.

**REMEMEBER: remove all protective plastic on ALL parts of the heater.

Chimney Pipe

The location and configuration of the chimney stack is very important to the

operation of the heater. A long, straight chimney stack will ensure a strong

draft for correct operation. The diameter of the chimney must be what is

specified. We recommend that the length of your chimney is a straight 5-6ft

run with a minimum of 4ft long and a maximum of 10ft. Avoid using elbows

and if necessary, use 45 degree elbows and allow for as much straight pipe

as possible with a minimum of 12” (28 cm) from the top of the heater. There

is no connector to connect the chimney pipe to the heater. There is a flue

collar already attached to the top of the heater and the pipe can attach by

squeezing the pipe into an oval shape and fitting it over the flue collar.

Chimney Pipe Diameters

All Sig Heaters- 3” diameter chimney (7.5cm)

Barometric Damper

We have 2 options for installing the barometric damper into your chimney.

You can either have the barometric attached to a 22” stainless pipe to be the

first piece of pipe of your chimney off the top of the heater or a 7” piece of

pipe that you can fit into your chimney 12” to 24” from the top of the heater.

All model heaters:

Part# S16-001: 3” x 22” stainless pipe with barometric

Part# 900287: 3” x 7” stainless pipe with barometric

The barometric damper should be installed in oil and solid fuel heaters. The

purpose is to maintain a strong draft without causing too much air to the

“fuel to air” mixture. When the damper is adjusted, the draft is altered by

allowing air to be pulled into the chimney by the air inlet on the damper and

not pulled into the burner. This gives you more control. Having a barometric

allows you to burn your heater at lower temperatures giving you the control

to adjust the draft once the fuel is adjusted to ensure a clean burn.
