Operation

Before you light your heater here are a few considerations.

Your new Morsø heater is approved for use with Solid Wood Fuel Only. DO NOT OVERHEAT. If the heater

or chimney connector glows, your heater is overheating. Use Morsø stove thermometer for correct

operating temperature (#62901200).

Have your chimney inspected and cleaned at least once a year by an approved and certiﬁed chimney

sweep.

Be aware; if the heater is not operated or installed in accordance with the manufacturers instructions

or the fuel quality is poor, creosote buildup may occur within the ﬂue thus increasing the risk of a

chimney ﬁre.

To reduce the risk of smoke and ﬂame spillage, operate the heater only with door(s) fully closed.

Caution:

Your heater will be hot while in operation. Keep children, the inﬁrm, clothing and furniture protected at

all times.

Choosing your fuel

All types of natural wood can be burned in your heater, but it must be well-seasoned and dry.

For the correct combustion efﬁciency and heat output, wood fuel should contain no more than 18%

moisture; this can easily be checked by using the Morsø Wood Moisture Meter (part # 62929900).

When wood fuel is cut to length you should allow for an inch gap between the fuel and side walls of the

ﬁrebox so as to ensure adequate circulation of the gases. Cut wood should also be split down middle to

allow for the quick release of moisture.

To naturally season wood fuel, it should be stacked and stored under cover in an airy location where

fresh air can move around the stack. Some soft woods may take as little as one good summer to sea-

son whereas harder woods such as oak, maple, and elm may require up to 18 months or more.

Avoid burning overly dry wood that is gray in color as under certain conditions it can cause performance

problems, such as back-pufﬁng and poor performance. Well seasoned wood will be light to hold and

when looking at the ends it will show signs of cracking from the center outwards.

If your wood spits or sizzles when burned and your heater’s door glass persistently clouds up, it is pos-

sible that your wood is not properly seasoned (although a poor chimney draft can also cause this).

Never use drift wood (from the sea) as salt content may cause corrosion; construction wood that may

have been impregnated with chemicals should also be avoided.

Starting the ﬁrst ﬁre

When lighting your heater for the ﬁrst time or after dormant periods, the initial ﬁre should be fairly

gentle so that the ﬁnish paint can cure and the main cast plates of the heater can expand gently and

settle into position.

The heater paint cures at higher temperatures and it should be expected that during the initial ﬁring

process a slight odor will be emitted into the room therefore, it is important to ventilate the room well

during this process.

The operating position of the air control lever (or dial) will vary and so will your loading intervals; both

are dependent on several factors, your lighting technique, the chimney draft, the fuel used and the heat

requirement etc.

Some basic techniques are outlined below.

In most models the heater is equipped with three air supplies:

Primary air is controlled by the air control lever situated beneath the ash lip or above the door, in some

models, on the door. Primary air passes through internal channels where it is preheated and eventually

washes at high speed down the back face of the door glass – the air-wash system. This super-heated

air helps to achieve high combustion efﬁciency of the volatile gases driven from the fuel.

Secondary air is factory-set and enters the combustion chamber via the bafﬂe assembly (or tubes)

located under the roof of the ﬁrebox. This source of combustion air mixes with the volatile gases and

given the right conditions, secondary combustion takes place making for very clean and low emissions.

This air supply is constant and cannot be varied.

Pilot air or tertiary air enters the combustion chamber through a hole located behind the front bottom

section of the ﬁre opening (below the front grates). This air ensures the embers in the ﬁre bed stay hot.

Pilot air supply is factory-set and cannot be varied.

Lighting and loading procedure

When you are ready to light your heater, it is essential to quickly establish a chimney draft therefore

the initial lighting process will require you to leave the door cracked open for a few minutes. For added

safety, it is of course essential that you pay close attention to the heater at this point.

During the process it is also important to create and maintain a good bed of ash (1” thick) in the ﬁre

bed. To achieve this be prepared to use 4-6lbs of dry kindling (thin sticks) during the initial lighting

process.

Before your start the lighting process fully open the primary air control lever (or dial).
