EMPYRE PRO SERIES INSTALLATION AND OPERATION MANUAL 11
INSTALLATION
Outdoor Furnace Installation
We recommend that the furnace be installed by a
qualied installer.
1. Position furnace on pad. Note: Lift only by
top lifting hook or bottom forklift guides. Use
caution! Furnace is heavy.
2. Identify and remove components shipped in
thefurnace:light,ashrake,uecleanouttool
(inreboxorrearoffurnace).
Outdoor Chimney Installation
Install a 1 inch (2.54cm) insulated chimney that is
listed to ULC-S610 and ULC- S604 standards. Apply
a bead of high temperature silicone on the outside
of the chimney (see Figure1, Page 12).
For tall chimneys, chimney braces are recommended.
Pro-Fab recommends a minimum chimney length
of 5 feet (1.52m).
IMPORTANT: A spark arrester must be installed if
theProSeriesfurnaceisusedinahighreriskarea.
Indoor Chimney Installation
When installing a new chimney ue, be sure to
observe local building codes and the National Fire
Protection Association rule: the top of the chimney
must extend at least 3.0 feet (0.9 m) above the
highest point where it exits the roof and be at least
2.0 feet (0.6 m) taller than any point of the roof
within 10.0 feet (3.04 m).
For a new chimney, use an insulated stainless steel
system that conforms to type HT (High Temperature)
requirements of UL 103 and ULC S629 and complies
with the requirements of Chapter 11 of NFPA 211,
Standard for Chimneys, Fireplaces, Vents and Solid
Fuel-Burning Appliances. Sections of stove pipe
(minimum 24 gauge black or blued steel) may be
used from the furnace to the insulated chimney.
Note: avoid using 90° Elbows; 45° is preferred.
A chimney cap must be installed.
Lining masonry chimneys with a stainless steel
liner is recommended.
Furnace Flue Diameter
Pro Series 200 6 inches (15 cm)
Pro Series 400 8 inches (20 cm)
IMPORTANT: DO NOT install furnace in a mobile
home or trailer.
Supplying Make Up Air
Fireplaces, other furnaces, clothes dryers, exhaust
fans, and other appliances all draw air from the room
in which they are located. The Pro Series adds to that
draw, making it important to ensure there is an ad-
equate source of fresh air to offset these demands.
Otherwise, a negative pressure may be created in
the room and starve combustion in the furnace.
1. Determine the volume of space (cubic feet) in
the room. Include in the calculation adjacent
rooms and areas not closed off by doors.
Volume (CF) = Length (ft) x Width (ft) x Height (ft)
2. Determine the air input requirements of all ap-
pliances in the space. Add them and round the
total to the nearest 1000 BTU per hour.
3. Determine whether the space is ‘conned’ or
‘unconned’bydividingthetotalvolumeofthe
room by the total input requirements for all ap-
pliances in the room.
a. If the result is greater than or equal to 50
CF/1000 BTU per hour, then consider the
space‘unconned.’
b. If the result is less than 50 CF/1000 BTU per
hour,thenconsiderthespace‘conned.’
