It Just Has To Work, Episode 14, Replacing a Toyotomi Laser 30 with a Laser 300 Kerosene Heater

[@Bucky1836]

Yall are lucky to have kersonse like yall do...i buy jp4 for my kero stuff at local airport 🥴

Little late now but the exhaust/intake can rotate so you don’t need the spacer on the floor. Your exhaust elbow will just point up into the exhaust.

Ya, that would have worked! Never occurred to me I guess because all the other heater exhaust ports I have ever seen have been horizontal. Thanks!

How much is the expected life span of it? How much is it supposed to live

[@greghall_The_TechEditor]

I have seen 12 - 15 years before a rebuild is necessary.

EE2 is a no fuel condition. If the fuel line was run dry, there could be an air bubble stopping the flow of Kerosene. The external fuel filter (if there is one) could be blocked. The internal filter screen, that could be plugged. The fuel pump could also be faulty. Did you try pressing the red primer button once for 1 second and trying a restart? Send me your model number and I will provide you with a factory service manual if I have it. [e-mail]

This was so helpful, Greg! I’m about to upgrade my Laser 30 and no one told me I’d have to do modifications when I bought the 301. Do you have a link the fire valve that ended up working? Thanks!

[@greghall_The_TechEditor]

Sure! www.supplyhouse.com/Firomatic-12840-FIROMATIC-3-8-ODF-Fusible-Inline-Valve-w-Flare-Nuts. I was told that the switch could not be done w/o cutting a new hole. Well with the new shiplap wall, that wasn't going to happen! So using only the old parts from the 30, I was able to get the intake and exhaust connected on the 300. The only part I needed was the fire valve aside from some copper lines and compression fittings. Luckily, all the Lasers use the same exhaust!

[@AlaskaBrooke]

@@greghall_The_TechEditorthanks for the link! Yeah, I have a nice relatively new tongue and groove wall I’m not putting a new hole in either!

[@bertoldriesenteil1430]

Is the exhaust pipe very loud?

[@greghall_The_TechEditor]

Inside the house it can not be heard. Outside it is more of a whir, like from a low pitched fan, probable no more than slow conversation level.

You should have read the MANUAL. First of all, the Vent need to be replaced with a new Heater. Second, you do not need the Fire Matic Valve. The 300 Series has this Safety Device built in the Fuel Sump. But not bad for the price and no Warranty.

[@greghall_The_TechEditor]

I did not receive a 300 manual with the heater. I looked in the 301/302 manual and the exploded diagram does not show an internal fire valve nor is it listed in the safety items on page 3. Plus on page 32 it states:"NOTE: An additional shut-off valve installed next to the heater will minimize fuel to be drained should the heater have to be disconnected. If the valve is on interior side, a fusible link type is recommended." Therefor I stand by my installation as correct. The exhaust vent for the 300 series is the same as the 30. According to here: www.ruralenergy.com/20479891-toyotomi-flue-pipe-4-to-9-all-models, it fits all models of Laser heaters. Rotating the unit provides customization during installation. Therefor replacing a serviceable exhaust with the exact same model is foolish. These exhausts are designed for decades of service.
