Ducting, white for Marquee heaters
This ducting is used in conjunction with the Duct diffuser (2212). The ducting fits onto either heater at one end and to to the Duct diffuser at the other. This allows the heater to be placed outside the marquee and to duct the air underneath the marquee wall. (LB White ref 26347- was 20685.)
- We only recommend Ducting No 2211 for this heater. It is a maximum of 3m long though it can be shorter. It has a tight helix in the spring, which does not allow excess folds when compressed to restrict the flow. Ideally this also should be kept as straight as possible. Tight kinks or using other non standard ducting even of the right diameter can cause high limit switch trip outs.
