newly purchased Mt Vernon E2 insert has a hand held remote due to the installer stating the wall mount can not be any further away from insert than 10 ft that would mean being in the same area of main heat - but I want the heat to regulate down the hall so they handed me a remote - now for all the forums I've read no one has mentioned using a remote. So my question is why does it turn off the heat source ( insert) when no activity for 6 hours, I now wake with no heat and deal with restarting. Should I install the wall mount thermostat - will it override( keep the fire going)? during the wee hours so I can sleep and wake to warmth.
