Retrospective blog...
Back on October 21st I covered the install of the airbox and horn, I also promised to cover the heater and front suspension install. Unfortunately, I forgot to follow up on both, I must have been busy. Apologies if you've been looking for the related content.
The installation of the heater is very simple and doesn't require much of an explanation, however for completeness I'll briefly cover it off with some photos as it's handy for builders when planning or performing research on their next task. I am composing this from memory so apologies if it's a little thin on specifics. Caterham's own documentation within the new Ikea manual is pretty good for the installation of the heater so I'd recommend referring to that also.
The heater assembly in my kit was provided in a dedicated cardboard box. The unit is essentially constructed in two distinct pieces, the part which sits in the engine bay against the bulkhead, and the vent section which sits in the cockpit under the dash. The two pieces are attached together for shipping and so need to be separated before they can be fitted. They're joined together with the hardware used during the installation too, so finding the correct nuts and bolts is pretty straightforward.
There are two different types of retaining plates used within the hardware, a straight type used on the vent side and a slightly curved type on the engine bay side. The whole assembly is held in place using bolts which pass through the plates and the assembly plastic, the lower two bolts are passed from the vent side out, whilst the top bolt is from the engine bay in. Caterham predrills all the holes required in the bulkhead along with the aperture to support the heat exchanger.
Once you've separated the two halves of the heater it's important to add a grommet to the electrical cable. To do this the grommet will need cutting open so that it can bypass the cable's connector which is too wide for the grommet to pass over. Use a drop of superglue to make the grommet hole again, and ensure it moves freely on the electrical cable.
When mounting the heater against the bulkhead ensure the cable is passed through under the dashboard first and the grommet secured into the notch at the top of the heater cut out. You should find a receiving connector immediately under the dash where the cable comes through.
Assuming you've secured the heater with the appropriate nuts and bolts, the only remaining task is to remove the rubber bungs from the heater's pipework.
