I installed the stove (Harman XXV) a couple of months ago and have been running it pretty much daily. Naturally ash will build up at the front of the fire pot and as it builds it appears to restrict the width of flames base. This apparent restriction doesn't seem to affect the heat output, but I've been wondering if there may be any loss of efficiency by not routinely pulling the ash build up off to ensure the holes have free air flow. Usually every 2-3 days or when the flame is idle between calling for heat I do clean the fire pot front, but wondering if I should do it more frequently to keep it clear, such as the morning and evening.
Also I've noticed reference to "scraping" the fire pot in a few threads which infers a build up of a hard crusted residue. Simply pulling the ash off of mine reveals the bare metal and no holes appear clogged or otherwise. Does the grade of the pellets tend to leave this cleaner? I've been using Geneva's from the onset of firing the stove.
