If you are having trouble meeting the gap tolerance of 1/4" to 1/2" between joints, there is a solution.
The picture attached shows you can pack mortar into a joint to compensate for the larger gap.
The manual says do not pack joints so you oven doesn't crack during heating expansion.
However, packing a single joint is not an issue as the oven will expand outward from the solitary packed joint.
This will resolve any heat loss issues and doesn't present danger of damaging the oven.
