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.  
 
 

1.1 Items supplied with the fire
