4.1 Commissioning

Note:  It  is  the  responsibility  of  the  installer  to  ensure  that  the  appliance  is  properly 
commissioned  by  a  trained  and  competent  technician.  Failure  to  do  so  WILL  invalidate 
ALL warranties.

Before  commissioning  ensure  that  the  combustion  pot  and  ash  pan  are  in  place  as  they  may 
have been displaced during transport/installation (refer to Figure 14). Switch the appliance on, 
ensuring all controls are calling for heat.

The combustion settings are factory set and cannot be altered, the combustion fan works under 
negative pressure (draws exhausted air out of the combustion chamber) and is controlled by the 
differential pressure sensor and lambda sensor fitted to the appliance.  Fan speed will modulate 
depending on the auger feed rate. As the combustion fan is used to both pre and post purge the 
combustion chamber, a low minimum draft of 4pa is required.

Using  a  flue  gas  analyser,  check  the  CO

2

  content  and  the  flue  gas  temperature  once  the 

appliance is hot and in a stable operating condition. Testing while the appliance is still relatively 
cold gives inaccurate results and leads to incorrect adjustments being made. The CO

2

 

level is 

controlled  by  the  combustion  fan  and  is  self­correcting  and  should  not  require  alteration  at 
commissioning.  However,  if  the  CO

2

 

level  is  not  within  the  range  of  6  to  14%  please  contact 

Warmflow. 

If  the  flue  gas  temperature  is  above  140°C  or  a  CO  value  above  400ppm  consistently  please 
contact Warmflow. Please refer to Table 1 for flue gas temperatures at maximum and minimum 
outputs. 

The  appliance  has  an  anti­condensation  valve  factory­fitted  which  must  not  be  removed  or 
tampered  with  in  any  way.  The  valve  is  controlled  by  the  appliance’s  user  interface  controller 
and will ensure a return temperature of 55°C to promote longevity of the heat exchanger. 

Note: All product warranties will be invalidated if the appliance is not commissioned by a 
Warmflow  engineer  or  other  trained  and  competent  technician  and  the 
installation/commissioning  certificate  (see  Section  6  of  this  manual)  completed  and 
returned to Warmflow within 30 days from the date of installation and 90 days from the 
date code stamped on the appliance.

Additionally,  to  comply  with  building  regulations,  a  copy  of  the  completed 
installation/commissioning certificate must be left with the householder.

4.2 Servicing

4.2.1 General Requirements

The appliance must be serviced at least annually or as indicated by the user interface controller 
by a Warmflow Engineer or other competent technician. This is necessary in order to optimise 
performance of the appliance and to ensure its efficiency and safety for the user.  Additionally, 
when servicing, special attention should be paid to the condition of the combustion pot, cleaning 
knives  and  mechanisms,  air  turbulators,  door  insulation,  sealing  rope,  ash  pan,  hopper  door 
seal and auger assembly. If found to be defective, they must be replaced.
