Spitfire Installation Instructions

The Spitfire Fireplace Heater with 4 tube Blower is easy to use and simple to install. The inside dimensions of your fireplace should be at least 1 to 2 inches wider on the sides and back than the heater itself. Then assemble the blower tubing to the heat exchanger tubes and place the unit into your fireplace. You will want to place the heater in the center of the fireplace with the tube protruding out of the front opening. 

The blower can connect to the right or left side of the unit. The tube is flexible and will stretch to a longer length to be able to install into almost any project.

Place wood on the unit's base and start a moderate fire which will achieve your best efficiency in heat
production. Be sure the damper is in the OPEN POSITION BEFORE LIGHTING THE FIRE. There
will be a smell as the first burn will burn off the oil in the tubes. This is normal. 

It is recommended to use a high temperature silicone sealant to make sure that all the connections are sealed properly. This will help increase the amount of warm air that is pushed into the living space.

A Fireplace Screen should always be used when a fire is burning and the Spitfire Fireplace Heater is in operation. Check out our selection of Fireplace Screens.

If you need help selecting the proper Fireplace Screen then check out the Choosing a Fireplace Screen article on our Resource Center.

Fireplace blower is designed to be used with wood burning fireplaces and can be used with Gas Logs as long as safety guidelines are always met.


  • The blower box should never be placed inside of the fireplace.
  • It is important to never overfill the box with firewood as over firing the unit can cause damage that is not covered under the manufacturer's warranty.
  • The blower helps to cool down the unit properly and as such: the unit should never be operated without the blower attached. 
  • In the case of a power outage you will need to remove the unit from your fireplace before lighting a fire.
  • Product Note: The product can be used with gas logs. However, the only time this product would be able to be used with gas is if the burner is able to fit under the unit.
  • The unit may be used with a fireplace door as long as the door is open during use and the tubes and exhaust are not blocked by the frame of the fireplace doors.
  • BEFORE YOU BURN: There will be a smell on the first burn as the oil in the tubes will burn off. This is normal. WARNING: If you have birds and animals in the house. They should be removed from the house on the first burn. People that are asthmatic and children should also not be in the area during the first burn. Not for use in see-thru fireplaces.

With a 1 year replacement warranty and universal sizing it's easy to see why the Spitfire Fireplace Heater - 4 Tube with Blower is one of the best fireplace blower kits on the market.

Is a blower on a fireplace worth it?

In most fireplaces, the majority of heat is lost up the chimney system. By utilizing a blower system such as the Spitfire Fireplace Heater - 4 Tube with a blower, you are able to push a lot of the warm air into the living space. The other benefit of a tube heater is that it is pushing clean convection air into the room, while the exhaust is still sent up the chimney.

How does a fireplace blower work?

The Spitfire Fireplace heater tubes act as a heat exchanger and as the fire burns above them, the steel tubing heats up and the attached blower unit pushes the warm air into the living space.

How to install fireplace blower?

The Spitfire Fireplace 4 tube heater with blower is easy to install. All you have to do is connect the blower to the heat exchanger tubes via a flexible tubing and plug the blower in. Then you place the unit inside of the firebox, while keeping the blower box outside of the fireplace. Then you start a fire and let the unit do all the work from there. Also here are the Spitfire Installation Instructions.

When does fireplace blower turn on?

This Spitfire Heater has a blower unit that has an OFF, LOW and High Setting. Once you get your fire burning, you simply turn on the blower and once the tubes start to heat up, air will start to push into the room. It is important to never operate the unit without having the blower unit turned on. The blower helps cool down the unit properly.

Can you add a blower to an existing fireplace?

As long as you have a single sided fireplace and the dimensions of your fireplace meet or exceed the minimum requirements for the blower then you can add a blower unit to your masonry or factory built wood burning fireplaces.
