INSTALLATION PREPARATION 

Installation Requirements Checklist 

Your Frontier Series should be installed by a Greenwood approved heating contractor who is thoroughly 
familiar with gas, oil, and solid fuel hydronic heating appliances.  Also, be sure to comply with local building 
codes, fire codes and other regulations when installing the hydronic furnace.  

These are guidelines; please refer to appropriate manual sections for further details: 

Thoroughly read this entire manual and follow all instructions. 

Hire a licensed contractor with certified Greenwood installer training and experience in design and 
installation of hand-fired hydronic heating systems to install your Frontier Series hydronic furnace. 

Use caution when moving this furnace.  The Frontier Series hydronic furnace weighs about 1,500 lbs 
(680 kg) and serious injury can occur if you do not have the proper equipment and experienced 
manpower available. 

Comply with local building codes, fire codes and other regulations when installing this furnace and 
adhere to minimum clearances  and  restrictions. 

DO NOT install the Frontier Series furnace in a mobile home or trailer.  Instead, install the furnace 
outside in a fully enclosed structure and pipe the hot water into the mobile home.

Chimney and Venting 

Make sure to identify sources of make-up air in the room where the furnace is located.  The Frontier 
Series furnace, exhaust fans and other appliances all draw air from the room.  Be certain there is an 
adequate source of fresh air to offset these demands or you may create negative pressure in the room 
and starve the furnace of air needed for combustion resulting in poor burn performance and draft 
problems in your flue. Make sure that air entering the furnace is above 40°F (4.5°C). 

Connect the Frontier Series furnace to a properly installed and operating chimney which is vented to 
the outside.  Use an approved masonry or a UL 103 HT and ULC S629 Listed Residential Type and 
Building Heating Appliance Chimney (double or triple wall insulated flues).  

DO NOT

 vent the furnace to another room or inside a building.  Install with a dedicated chimney 

only.  

DO NOT

 share the chimney with another appliance.  Be sure your chimney is safely 

constructed and in good repair.  Before furnace installation, have the chimney inspected by a 
qualified inspector.  

DO NOT 

connect the furnace to an aluminum Type B gas vent. 

As with any furnace operated indoors,

 install a carbon monoxide monitor 

and take any other safety 

precautions to maintain safe oxygen levels in the room where the furnace is installed.

Plumbing and Controls 

The Frontier Series hydronic furnace is managed by an onboard controller (see “Operating the 
Furnace, Control Panel”).  Once the hydronic plumbing and chimney are in place per your 
installation the unit is ready to plug into a 

surge protected

 outlet and start heating your application. 

This hydronic furnace is designed to protect itself from low water temperature returns.  This prevents 
condensation within the boiler which will lead to poor performance and ultimately damage.  Make 
sure that the unit’s piping conforms to required specifications.
