2. General Information
2.1 Performances
Values are as measured per test method, except for the recommended heating area, firebox volume,
maximum burn time and maximum heat output.
Model Deco Alto (DB03220)
Type of combustion Non-catalytic
Fuel Type Dry Cordwood
Recommended heating area (sq. ft..)1 500 to 2,100 ft2(47 to 195 m2)
Overall firebox volume22.4 ft3(0.068 m3)
Loading volume EPA 1.95 ft3(0.055 m3)
Maximum burn time18 hours
Maximum heat output (dry cordwood)3 75,000 BTU/h (22 kW)
Overall heat output rate (min. to max.)2 4 14,200 BTU/h to 44,500 BTU/h
(4.16 kW to 13.04 kW)
Average overall efficiency3
(Dry cordwood) 72 % (HHV)577 % (LHV)6
Optimum efficiency7 79 %
Optimum overall efficiency8 76 %
Average particulate emissions rate9 2.3 g/h (EPA / CSA B415.1-10)10
Average CO11 69 g/h
1Recommended heating area and maximum burn time may vary subject to location in home, chimney draft,heat loss factors, climate, fuel type
and other variables. The recommended heated area for a given appliance is dened by the manufacturer as its capacity to maintain a minimum
acceptable temperature in the designated area in case of a power failure.
2The overall rebox calculation is an approximation and is not intended to be used for loading. This volume includes a buffer zone to allow an easier
fuel insertion, prevent ash spillage and allow the air wash to work properly.
3The maximum heat output (dry cordwood) is based on a loading density varying between 15 lb/ft3and 20 lb/ft3. Other performances are based on
a fuel load prescribed by the standard. The specied loading density varies between 7 lb/ft³ and 12 lb/ft3. The moisture content is between 19%
and 25%.
4As measured per CSA B415.1-10 stack loss method.
5Higher Heating Value of the fuel.
6Lower Heating Value of the fuel.
7Optimum overall efciency at a specic burn rate (LHV).
8The optimum heat transfer efciency is for the low burn rate and represents the appliance's ability to convert the energy contained in the wood logs
into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.
9This appliance is ofcially tested and certied by an independent agency.
10 Tested and certied in compliance with CFR 40 part 60, subpart AAA, section 60.534(a)(1(ii) and ASTM E3053-17. Based on ALT-125 sent by EPA on
February 28th, 2018.

2 Mobile homes (Canada) or manufactured homes (USA): The US Department of Housing and Urban Development describes “manufactured homes”
better known as “mobile homes” as follows; buildings built on xed wheels and those transported on temporary wheels/axles and set on a permanent
foundation. In Canada, a mobile home is a dwelling for which the manufacture and assembly of each component is completed or substantially
completed prior to being moved to a site for installation on a foundation and connection to service facilities and which conforms to the CAN/CSA-
Z240 MH standard.

2.4 EPA Loading
The loading methods shown below are those that were used during emissions certification.
2.4.1 Air control
The air control is located underneath the ash shelf.
To open the air control, pull the air control handle
completely (High). This will increase the burn rate.
To close the air control, push the air control handle
completely (Low). This will decrease the burn rate.
2.4.2 High burn rate (primary air control open)
Open the air control completely. Place height small
pieces (2" x 2") of wood in the firebox crossing them
at the greatest possible angle. Criss cross 10 to 16
kindling wood pieces on the small pieces of wood in
three layers at the greatest possible angle. Tie knot
with five sheets of paper and place them on top of the
kindling wood. Light up the paper and let the door ajar
at 90° until all the kindling wood is on fire and the first
row of small pieces of wood is on fire too. Close the
door. When there is no more fire in the front of the firebox and there are only faint flames on the
wood in the back of the firebox, break ashes, level the coal bed and put five logs in the firebox.
Put 3 pieces on the coal bed, without air space between them. Leave one inch of air space
between the rear firebrick and the first piece. The two other pieces should be added on top of
the first 3, in an East-West configuration. Let the door ajar to leave a space of one inch on the
door handle’s side for 1 minute maximum and then close the door.
2.4.3 Medium and low burn rate
On a two inches thick coal bed that is still red, place three logs in an East-West orientation.
There should be air space between each log and between the logs and the bricks. The two other
pieces should be added on top of the first three, slightly angled of 20°. Let the door ajar at 90°
for approximately 5 min. Then, close the door with the primary air control open. Leave to burn
with the primary air control open for approximately 10 more minutes and then close the primary
air control completely for the low burn rate and halfway for the medium burn rate. For better
results, close the air control gradually from the closing of the door to the complete closing of
the air control

3. Clearances to Combustible Material
The clearances shown in this section have been determined by tests according to procedures
set out in safety standards ULC S627 (Canada), UL 1482 (U.S.A.) and UL 737 (U.S.A.). When
the stove is installed so that its surfaces are at or beyond the minimum clearances specified,
combustible surfaces will not overheat under normal and even abnormal operating conditions.
No part of the stove or flue pipe may be located closer to combustibles than the minimum
clearance figures given.
Clearances may only be reduced by means approved by the regulatory authority.
The clearances to combustible walls may be slightly different in Canada and the U.S.A. and may
also differ depending on whether single or double wall flue pipe is used. Make sure to choose
the correct clearance for the stove location and type of flue pipe.
The clearances of the appliance and the flue pipes must be met individually, meaning the appliance
cannot be installed closer to the combustible materials than the single or double wall pipe allows.
For a safe way to reduce clearances refer to section"5. Reducing Wall and Ceiling Clearances Safely"
of this manual.
