1.0 Introduction
Congratulations!
You are the owner of a state-of-the-art Ultra Low Emission Burner
“Masport
Cromwell”
designed and developed by Glen Dimplex New Zealand. Thank you for purchasing a Masport
appliance.
CROMWELL
burner is a new generation wood fire, designed to provide you with all the warmth and charm of
a fireplace, at the same time have negligible emissions with dramatically reduced impact on the environment.
Environment Canterbury has approved installation of this burner in all clean air zones that have been banned
for installation of a conventional wood burner. As it bears the Masport brand, it promises to provide you with
economy, safety, and efficiency.
To make the most of your appliance, it is important to install, operate and maintain the burner correctly.
Please read this installation and operations manual carefully before installing or operating your CROMWELL
fire. Please take time to understand the basic principles of this new burner which uses down draft
combustion technique.
Conventional Masport burner has a single firebox and uses triple combustion technique with preheated
combustion air. Injection of preheated air jets in different direction bombards the fire bed and creates a very
hot turbulent flame to burn most of the polluting particles at around 600~700
o
C. Though this is a clean way
of burning, some particulate and valuable heat energy escapes to atmosphere through an exhaust flue pipe.
Cromwell burner has a firebox with two combustion chambers and a heat exchanger at the rear of these two
chambers. Fuel is loaded and ignited in the top combustion chamber where primary combustion takes place.
After initial primary burning, when the overall burner is hot enough and sustained flue draft is created, flue
gases are directed downward into bottom combustion chamber by closing the damper in upper section of the
firebox. The exhaust gases passing through the red-hot embers get re-ignited and burns at temperatures
higher than 1000
o
C. The extreme hot temperatures and turbulence created while passing through ember
bed, burns almost all the particulate matter. Further, these hot gases pass through a heat exchanger to
extract maximum heat from the exhaust gases which creates a much lower temperature flue gas than the
conventional wood burners. Overall, the downdraft combustion technique is more effective and efficient way
of burning wood which give negligible emissions, returns maximum heat from the fuel burnt and reduces fuel
consumption.

1.2 Handling and Transport

Single person handling could cause injury, hence Masport recommends suitable handling equipment or two
persons while handling, both outside and inside the house.
Removing both top and bottom doors, Injector and ceramic block will help to reduce weight the weight and
will ease handling of fire during installation.
All precautions have been taken during designing of packaging so that the fire reaches customer’s house
without any damage. In case any damage is found while opening the fire, please report it to your dealer and
to Masport immediately before installing the fire.
