In particular, when first lighting a wood fire, the Morso says that only
secondary air is used;

I find that the lever that controls air jams with ash and has to be
tapped to move it. As I never use it with coal I suspect the primary air
passage is blocked because if I push the lever left the fire goes out.

Fortunately I haven't had ash block any lever.


Anyway I find lighting this fire almost impossible without the air
control fully to the right and the door seal cracked open.

Mine will light with the door closed, but when I top it up with logs I
have to leave it open to get the new wood alight properly.

The worse problem I had with the Scan is a safety design issue really.
One day I topped it up and closed the door after the new wood was
roaring away. When the door is closed the fire usually goes down
somewhat, but this time it didn't. It was just like a few weeks earlier,
when I'd had to replace the ceramic rope as it had become compressed,
and air was leaking in past it. But as I'd replaced that, it couldn't be
the cause. I then saw the fire inside, through a gap between the stove
body and the door. I thought I hadn't shut the door properly, so
refitted the removable handle and turned it to reclose the door. It made
no difference. I shut down the airwash completely, but like yours, there
is no control over the tertiary air. I then had to hold the door closed
until the fire went down. After the wood had burnt low, I opened the
door and found the bolt holding the latch was loose. I tried tightening
it, but it just turned. I removed it completely to find the end threads
were stripped! Luckily I had a spare 5mm bolt of the right length and
use that to hold the latch. It worries me that, if that screw fails,
there is no way the latch will hold the door closed, and no way anything
else can hold the door closed as the catch for the latch is internal and
inaccessible.
